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and rich cultural and historical content needed for the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.

Mark the statements below as TRUE (T ) or FALSE ( F) according to Text 1. ( ) Tourism may actually be quite beneficial to some degraded mining areas. ( ) Mining tourism has recently been promptly embraced by Brazilian regions. ( ) Ouro Preto is attracting people because mining is one of its most recent activities. The correct sequence 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.
