To troubleshoot hardware problems
1. If your computer beeps when you start it but does not
display anything on your monitor:
a. Disconnect and reconnect your monitor from your
computer.
b. Verify that your monitor's power cord is connected
and that your monitor is turned on.
c. If possible, connect your monitor to a different
computer to make sure that your monitor works
properly.
d. If your monitor works but your computer beeps
and displays nothing, your video adapter has
probably failed. If your computer is under warranty,
contact your computer manufacturer for support. If
your computer is not under warranty, and you are
comfortable opening your computer's case and
replacing internal hardware, purchase and install a
compatible replacement video adapter. Otherwise,
contact a service center for assistance. While
replacing a part is a nuisance and may be costly,
your documents, pictures, and e-mail should be safe
and will be available when your computer is fixed.
2. If you see an error message that indicates that a keyboard
is not present or a key is stuck, turn off your computer and
reconnect your keyboard. If the problem continues, replace
your keyboard.
3. Sometimes your computer won't start because your
computer is not compatible with a hardware accessory. If
you have recently added a new hardware accessory, turn
your computer off, remove the accessory, and restart your
computer.
4. Remove all hardware accessories except your keyboard,
mouse, and monitor. If your computer starts successfully,
shut down Windows, turn off your computer, and add
one hardware accessory. Then, restart your computer. If
your computer fails to start, the hardware accessory you
most recently added is causing a problem. Remove the
hardware and contact the hardware vendor for support.
You can reconnect other hardware accessories.
5. You may have a loose connector. Turn off your computer,
remove all connectors from the outside of your computer,
and then carefully push the connectors back in. Look for
stray wires, bent pins, and loosely fitting connectors.
6. If you are comfortable opening your computer's case,
shut down your computer, unplug the power, and open
your computer's case. Remove and reconnect all cables.
Remove and reconnect all cards inside your computer,
including your computer's memory chips. Reassemble
your computer before attempting to start it again.
7. If your computer still doesn't start, your motherboard,
processor, memory, or graphics card may have developed
a problem. While failed hardware can be frustrating, your
documents, pictures, and email should be safe and will be
there when your computer is fixed.

In the excerpt of item 7 of the text – While failed hardware can be frustrating, your documents, pictures, and email should be safe – the word “while” can be correctly replaced by
Mining tourism in Ouro Preto
Ouro Preto is surrounded by a rich and varied natural
environment with waterfalls, hiking trails and native vegetation
partially protected as state parks. Parts of these resources are
used for tourism. Paradoxically, this ecosystem contrasts with the
human occupation of the region that produced, after centuries, a
rich history and a cultural connection to mining, its oldest
economic activity which triggered occupation. The region has an
unlimited potential for tourism, especially in specific segments
such as mining heritage tourism, in association or not with the
existing ecotourism market. In fact, in Ouro Preto, tourism,
history, geology and mining are often hard to distinguish; such is
the inter-relationship between these segments.
For centuries, a major problem of mining has been the reuse of
the affected areas. Modern mining projects proposed solutions to
this problem right from the initial stages of operation, which did
not happen until recently. As a result, most quarries and other
old mining areas that do not have an appropriate destination
represent serious environmental problems. Mining tourism
utilizing exhausted mines is a source of employment and income.
Tourism activities may even contribute to the recovery of
degraded areas in various ways, such as reforestation for leisure
purposes, or their transformation into history museums where
aspects of local mining are interpreted.
Minas Gerais, and particularly Ouro Preto, provides the strong
and rich cultural and historical content needed for the
transformation of mining remnants into attractive tourism
products, especially when combined with the existing cultural
tourism of the region. Although mining tourism is explored in
various parts of the world in extremely different social, economic,
cultural and natural contexts, in Brazil it is still not a strategy
readily adopted as an alternative for areas affected by mining
activities.

The problem referred to in “solutions to this problem” (l. 14-15) is:
TEXT 2
Innovation is the new key to survival
[…]
At its most basic, innovation presents an optimal strategy for
controlling costs. Companies that have invested in such technologies
as remote mining, autonomous equipment and driverless trucks and
trains have reduced expenses by orders of magnitude, while
simultaneously driving up productivity.
Yet, gazing towards the horizon, it is rapidly becoming clear that
innovation can do much more than reduce capital intensity.
Approached strategically, it also has the power to reduce people and
energy intensity, while increasing mining intensity.
Capturing the learnings
The key is to think of innovation as much more than research and
development (R&D) around particular processes or technologies.
Companies can, in fact, innovate in multiple ways, such as leveraging
supplier knowledge around specific operational challenges,
redefining their participation in the energy value chain or finding new
ways to engage and partner with major stakeholders and
constituencies.
To reap these rewards, however, mining companies must overcome
their traditionally conservative tendencies. In many cases, miners
struggle to adopt technologies proven to work at other mining
companies, let alone those from other industries. As a result,
innovation becomes less of a technology problem and more of an
adoption problem.
By breaking this mindset, mining companies can free themselves to
adapt practical applications that already exist in other industries and
apply them to fit their current needs. For instance, the tunnel boring
machines used by civil engineers to excavate the Chunnel can vastly
reduce miners' reliance on explosives. Until recently, those machines
were too large to apply in a mining setting. Some innovators,
however, are now incorporating the underlying technology to build
smaller machines—effectively adapting mature solutions from other
industries to realize more rapid results.
Re-imagining the future
At the same time, innovation mandates companies to think in
entirely new ways. Traditionally, for instance, miners have focused on
extracting higher grades and achieving faster throughput by
optimizing the pit, schedule, product mix and logistics. A truly
innovative mindset, however, will see them adopt an entirely new
design paradigm that leverages new information, mining and energy
technologies to maximize value. […]
Approached in this way, innovation can drive more than cost
reduction. It can help mining companies mitigate and manage risks,
strengthen business models and foster more effective community
and government relations. It can help mining services companies
enhance their value to the industry by developing new products and
services. Longer-term, it can even position organizations to move the
needle on such endemic issues as corporate social responsibility,
environmental performance and sustainability.

NASA Researchers Studying Advanced Nuclear
Rocket Technologies
January 9, 2013
By using an innovative test facility at NASA's Marshall
Space Flight Center in Huntsville, Ala., researchers are able to
use non-nuclear materials to simulate nuclear thermal rocket
fuels – ones capable of propelling bold new exploration missions
to the Red Planet and beyond. The Nuclear Cryogenic
Propulsion Stage team is tackling a three-year project to
demonstrate the viability of nuclear propulsion system
technologies. A nuclear rocket engine uses a nuclear reactor to
heat hydrogen to very high temperatures, which expands
through a nozzle to generate thrust. Nuclear rocket engines
generate higher thrust and are more than twice as efficient as
conventional chemical rocket engines.
The team recently used Marshall's Nuclear Thermal
Rocket Element Environmental Simulator, or NTREES, to
perform realistic, non-nuclear testing of various materials for
nuclear thermal rocket fuel elements. In an actual reactor, the
fuel elements would contain uranium, but no radioactive
materials are used during the NTREES tests. Among the fuel
options are a graphite composite and a "cermet" composite – a
blend of ceramics and metals. Both materials were investigated
in previous NASA and U.S. Department of Energy research
efforts.
Nuclear-powered rocket concepts are not new; the United
States conducted studies and significant ground testing from
1955 to 1973 to determine the viability of nuclear propulsion
systems, but ceased testing when plans for a crewed Mars
mission were deferred.
The NTREES facility is designed to test fuel elements and
materials in hot flowing hydrogen, reaching pressures up to
1,000 pounds per square inch and temperatures of nearly 5,000
degrees Fahrenheit – conditions that simulate space-based
nuclear propulsion systems to provide baseline data critical to
the research team.
"This is vital testing, helping us reduce risks and costs
associated with advanced propulsion technologies and ensuring
excellent performance and results as we progress toward further
system development and testing," said Mike Houts, project
manager for nuclear systems at Marshall.
A first-generation nuclear cryogenic propulsion system
could propel human explorers to Mars more efficiently than
conventional spacecraft, reducing crews' exposure to harmful
space radiation and other effects of long-term space missions. It
could also transport heavy cargo and science payloads. Further
development and use of a first-generation nuclear system could
also provide the foundation for developing extremely advanced
propulsion technologies and systems in the future – ones that
could take human crews even farther into the solar system.
Building on previous, successful research and using the
NTREES facility, NASA can safely and thoroughly test simulated
nuclear fuel elements of various sizes, providing important test
data to support the design of a future Nuclear Cryogenic
Propulsion Stage. A nuclear cryogenic upper stage – its liquidhydrogen
propellant chilled to super-cold temperatures for
launch – would be designed to be safe during all mission phases
and would not be started until the spacecraft had reached a safe
orbit and was ready to begin its journey to a distant destination.
Prior to startup in a safe orbit, the nuclear system would be cold,
with no fission products generated from nuclear operations, and
with radiation below significant levels.
"The information we gain using this test facility will permit
engineers to design rugged, efficient fuel elements and nuclear
propulsion systems," said NASA researcher Bill Emrich, who
manages the NTREES facility at Marshall. "It's our hope that it
will enable us to develop a reliable, cost-effective nuclear rocket
engine in the not-too-distant future."
The Nuclear Cryogenic Propulsion Stage project is part of
the Advanced Exploration Systems program, which is managed
by NASA's Human Exploration and Operations Mission
Directorate and includes participation by the U.S. Department of
Energy. The program, which focuses on crew safety and mission
operations in deep space, seeks to pioneer new approaches for
rapidly developing prototype systems, demonstrating key
capabilities and validating operational concepts for future vehicle
development and human missions beyond Earth orbit.
Marshall researchers are partnering on the project with
NASA's Glenn Research Center in Cleveland, Ohio; NASA's
Johnson Space Center in Houston; Idaho National Laboratory in
Idaho Falls; Los Alamos National Laboratory in Los Alamos,
N.M.; and Oak Ridge National Laboratory in Oak Ridge, Tenn.
The Marshall Center leads development of the Space
Launch System for NASA. The Science & Technology Office at
Marshall strives to apply advanced concepts and capabilities to
the research, development and management of a broad
spectrum of NASA programs, projects and activities that fall at
the very intersection of science and exploration, where every
discovery and achievement furthers scientific knowledge and
understanding, and supports the agency's ambitious mission to
expand humanity's reach across the solar system. The NTREES
test facility is just one of numerous cutting-edge space
propulsion and science research facilities housed in the state-ofthe-art
Propulsion Research & Development Laboratory at
Marshall, contributing to development of the Space Launch
System and a variety of other NASA programs and missions.

Read the text below to answer questions 16-20.
Background
The Naval Nuclear Propulsion Program (NNPP) started in
1948. Since that time, the NNPP has provided safe and effective
propulsion systems to power submarines, surface combatants,
and aircraft carriers. Today, nuclear propulsion enables virtually
undetectable US Navy submarines, including the sea-based leg
of the strategic triad, and provides essentially inexhaustible
propulsion power independent of forward logistical support to
both our submarines and aircraft carriers. Over forty percent of
the Navy's major combatant ships are nuclear-powered, and
because of their demonstrated safety and reliability, these ships
have access to seaports throughout the world. The NNPP has
consistently sought the best way to affordably meet Navy
requirements by evaluating, developing, and delivering a variety
of reactor types, fuel systems, and structural materials. The
Program has investigated many different fuel systems and
reactor design features, and has designed, built, and operated
over thirty different reactor designs in over twenty plant types to
employ the most promising of these developments in practical
applications. Improvements in naval reactor design have allowed
increased power and energy to keep pace with the operational
requirements of the modern nuclear fleet, while maintaining a
conservative design approach that ensures reliability and safety
to the crew, the public, and the environment. As just one
example of the progress that has been made, the earliest
reactor core designs in the NAUTILUS required refueling after
about two years while modern reactor cores can last the life of a
submarine, or over thirty years without refueling. These
improvements have been the result of prudent, conservative
engineering, backed by analysis, testing, and prototyping. The
NNPP was also a pioneer in developing basic technologies and
transferring technology to the civilian nuclear electric power
industry. For example, the Program demonstrated the feasibility
of commercial nuclear power generation in this country by
designing, constructing and operating the Shipping port Atomic
Power Station in Pennsylvania and showing the feasibility of a
thorium-based breeder reactor.
