Assinale a alternativa que contém a voz passiva da sentença: “Did the noise frighten them?”.
Google as well as Yahoo, Microsoft and AOL among
others are gearing up to keep a much closer eye on all of us,
so that within five years these and other firms will routinely
track our movements, friends, interests, purchases and
5 correspondence – then make money by helping marketers
take advantage of the information.
These companies' brash plans are pushing us toward a
thorny choice that will determine the future of computing.
Google and other Web-oriented, information-service giants are
10 determined to build a breathtaking array of services based on
your personal information, and they're betting you'll be willing
to share it with them in order for you to reap the benefits. But
if we cooperate and let them in on the details of our lives, we'll
lose much of our privacy, and possibly a lot more.
15 A privacy backlash, however, would stifle these potentially
revolutionary services before they get off the ground – and
leave the computer industry's biggest plans for growth in
tatters. That may be just what some people want. The U.S.
Congress is considering four bills that would make it illegal to
20 collect and share information online or through cell phones
about people without clearer warning and permission. These
sorts of restrictions are already in effect throughout much of
Europe, thanks in part to European Union directives on privacy
and electronic communications passed in 2002 and 2003.
25 The good news is that there's no reason to choose
between technology and privacy. New technologies are
emerging that can doctor our data so that companies know
just enough about us to ply us with customized services, while
preventing them from getting a clear picture of our private
lives. The question is again one of trust: in this case, whether
people will come to trust the companies that are trying to build
these new technologies.

Mark the one item which contains the best passive alternative for we'll lose much of our privacy (lines 13-14):
(abridged from Next Frontiers in Newsweek, April 3, 2006)
“is already offered” (l.33) can be replaced by has already been offered without changing the meaning.
applied an impressive array of innovative technologies to
improve productivity and efficiency, while yielding
environmental benefits. According to the U.S. Department
of Energy, "the petroleum business has transformed itself
into a high-technology industry."
State-of-the-art technology allows the industry to
produce more oil and natural gas from more remote
places - some previously unreachable - with significantly
less adverse effect on the environment. Among the
benefits: increased supply to meet the world's growing
energy demand, reduced energy consumption at oil and
natural gas facilities and refineries, reduced noise from
operations, decreased size of facilities, reduced
emissions of pollutants, better protection of water
resources, and preservation of habitats and wildlife.
With advanced exploration and production
technologies, the oil and gas industry can pinpoint
resources more accurately, extract them more efficiently
and with less surface disturbance, minimize associated
wastes, and, ultimately, restore sites to original or better
condition.
Exploration and production advances include
advanced directional drilling, slimhole drilling, and 3-D
seismic technology. Other segments of the industry have
benefited from technological advances as well. Refineries
are becoming highly automated with integrated process
and energy system controls; this results in improved
operational and environmental performance and enables
refineries to run harder and produce more products safer
than ever before. Also, new process equipment and
catalyst technology advances have been made very
recently to meet new fuel regulations requiring very low
levels of sulfur in gasoline and diesel.
Technology advances such as these are making it
possible for the oil and natural gas industry to grow in
tandem with the nation's energy needs while maintaining
a cleaner environment. The industry is committed to
investing in advanced technologies that will continue to
provide affordable and reliable energy to support our
current quality of life, and expand our economic horizons.
For example, we are researching fuel cells that may
power the vehicles of tomorrow with greater efficiency
and less environmental impact. We are investigating ways
to tap the huge natural gas resources locked in gas
hydrates. Gas hydrates are common in sediments in
the ocean's deep waters where cold temperatures and
high pressures cause natural gas and water to freeze
together, forming solid gas hydrates. Gas hydrates could
be an important future source of natural gas for our nation.
Some of our companies are also investigating
renewable energy resources such as solar, wind,
biomass and geothermal energy. By conducting research
into overcoming the many technological hurdles that limit
these energy resources, they hope to make them more
reliable, affordable and convenient for future use. Although
the potential for these energy resources is great,
scientists do not expect them to be a significant part of
the nation's energy mix for many decades. For this
reason, the industry must continue to invest in
conventional resources such as oil and natural gas. We
will need to rely on these important energy resources for
many decades to come.
