YOUTH PROLONGED: OLD AGE POSTPONED
by Robert Weale (King's College London, UK)
What exactly is human ageing? Can it be slowed down?
These questions have puzzled scientists and laymen alike
for generations, and continue to do so today. The author
addresses these thought-provoking issues by challenging
pre-conceived notions of age-perception, age-acceptance
and inter-age relations. Pertinent matters of age-related
communication are dealt with, and the reader is treated to
a grand tour of the latest theories of ageing, age-related
biological changes and age-related diseases, such as
Alzheimer's Disease. Here, the author's expertise in agerelated
eye diseases truly comes into its own.
Weale's unique work not only underlines important
genetic and avoidable risk factors but gives ample
consideration to possible consequences stemming from
different early lifestyles. Readers will re-consider their
ideas of what it means to age, and gain a better
understanding of what can and cannot slow down the
process of ageing.

Microsoft to Offer Free Virus Protection Software for
Windows

By ScottGilbertsonNovember 19, 2008

Microsoft plans to offer Windows users a new antivirus
package designed to protect the OS from viruses, spyware,
rootkits and trojans. The new software is tentatively code-
named Morro, and will be available for free to Windows XP,
Vista and 7 users sometime in the second half of 2009.
The new software will reportedly use very minimal resources,
which means it should work well with older PCs. If fact,
Microsoft says Morro has been specially designed for older
PCs and low-spec machines popular in developing nations. In
addition to its minimal processor demands, Morro has been
developed to use very little bandwidth,making it ideal for those
without broadband connections.
Morro will replace Microsoft's current, paid service, Windows
Live OneCare, which has been available on a subscription
basis for $50 per year.
While a free, antivirus solution that ships withWindows would
be a boon for the average user, it could also mean trouble for
third-party software solutions. Given that a bundled solution
could raise antitrust concerns -and would no doubt see
competitors likeMcAfee and Grisoft reaching for the lawyers-
Microsoftwill be offeringMorro as a separate download.
Assuming Morro can deliver decent security it should be a
welcome free addition to Windows, but we don't suggest
throwing away your third-party software just yet. Antivirus
software suites will likely continue to hold an edge over Morro
by offering additional handy tools - like passwordmanagers,
identity theft protection and browser-based phishing
protection.
Still, if you've been runningWindowswith no antivirus software
at all,Morrowill no doubt be better than nothing, and it's hard to
arguewith free.

You ___ not believe that these possibilties are real, they're based ___ experiments that ___proved until now.

This text refers to items from 16 through 25.

1           Japan and Korea are outstanding markets in terms
of the world's advances in cellular telephony, where
multimedia applications have surged into feverish
4 popularity. Users in these countries have demanded
 velocity and high quality data transmission - such as
 images, videos and sounds - as the principal distinctive
 7 features for the cellular telephone. Although the industry in
 Brazil is not yet experiencing the same phase as in the
 Asian countries, innovative third generation services,
 10 aligned with world-class technology, are already present,
 with data transmission speeds of up to 2.4 Mbps.
             In fact, in some cases, Brazil has held multimedia
 13 application launches simultaneously with the United States,
 tremendously increasing the economic and digital inclusion
 that cellular telephony has fomented in recent years. The
 16 heavy impact of mobile communication on Brazilian
 society can be measured by the expansion of the customer
 base, which has been growing at historic rates of 30% a
 19 year and now serves over 50 million customers. In other
 words, four out of every ten Brazilians have a cellular
 telephone.
 22          The importance of mobile telephony has already
 surpassed that of the traditional fixed telephone system,
 because the cell phone actually fulfills the function of
 25 taking communication to all levels of the population. Its
 widespread network has opened gateways to regions that
 formerly had not been benefited by the implementation of
 28 a fixed telephone system, such as, for example, many rural
 areas that are now mobile telephone customers.
              The responsibility that cellular telephony carries
 31 as an instrument for transforming people's lives tends to
 increase enormously in the short term. In Brazil, third
 generation CDMA 3G EVDO service is already offered and
 34 is able to provide handheld resources, similar to CD, DVD
 and TV, anywhere and at any time, based on Qualcomm's
 cutting edge CDMA technology.
 Internet: (with adaptations). 

 Based on the text above, judge the following items.
"is already offered" (R.33) can be replaced by has already been offered without changing the meaning.
