Read the following text to answer questions 15 to 18. Simply stated, computational linguistics is no more than the use of electronic digital computers in linguistic research. These machines are employed to scan texts and to produce, more rapidly and more reliably than is possible without their aid, such valuable tools for linguistic and stylistic research as word lists, frequency counts, and concordances. But more interesting and theoretically much more difficult than the compilation lists, is the use of computers for automatic grammatical analysis andtranslation. A considerable amount of progress was made in the area of machine translation in the United States, Great Britain, the Soviet Union, and France between the mid- 1950's and the mid-1969's, but much of the original impetus for this work has now disappeared, due in part to the realization that the problems involved are infinitely more complex than was at first envisaged. Thus, translation continues to remain as much anart as a science, ifnot more so.

TEXTO:

All for one and one for all is what we all should be.
But instead we go and fight each other.
Now, that wasn’t meant to be.
You know, the sun is there to light the day.
[5] The night is lit by the moon.
If we don’t come together, my brother, it all can end

[very soon.

It’s your world now.
The future is plain to see.
(Sing it, yeah. Sing it, yeah, yeah, yeah.).
[10] Give love right now.
We need the harmony.

TEXTO:

They can reach 2 meters in length, eat a little bit of

everything and are essential for the conservation of what

is left of their habitat, the Atlantic Rainforest. We are

referring to the caiman alligator.

[5] With the destruction of the natural environment, like

other species, the crocodilian reptile’s existence is being

threatened, and hunting is one of the culprits behind

their endangerment, according to the analysis of

conservationist Yhuri Nóbrega, from Project Caiman. “It’s

[10] a difficult issue to approach because it is cultural. At any

of our activities or lectures, we see that people have either

already tried crocodile meat or know someone who has,”

he says.

“In the interior of Bahia, especially near the São

[15] Francisco River, the meat is known as ‘the cod of the

river,’ because it is salted for preservation, and because

of the way in which it is commercialized,” explains

Luciano Verdade, a professor at USP and one of the

leading crocodile experts in Brazil. In the case of the

[20] Caiman latirostris (the caiman’s scientific name), the

issue is that the species generates economic interest,

both for its skin and its meat.

In what remained of the Atlantic Forest, there is

little space for the small communities, especially during

[25] the dry season. It is not difficult to find the crocodiles

outside of their natural environment. It is not unusual to

find them in settling ponds, near pig farming or breeding

pastures.

“Something similar occurs in the wetlands

[30] (Pantanal), but through a natural process. During the dry

season, the pond is reduced, creating a reserve of

bacteria that comes in contact with the crocodiles,” says

the professor. That contamination adds weight to the claim

that consuming crocodile meat from an unknown source

[35] may not be a good idea.

SCIENCE INCHES CLOSER TO A UNIVERSAL BLOOD TEST FOR CANCER

A universal blood test for any type of cancer is an oncologist’s dream come true, and a new study suggests this concept may soon become a reality. Research from the University of California, San Diego, has found a new way to detect cancer in the blood that could both alert doctors to the presence of cancer, and tell them where in the body the tumor is located.

The new study, published online in the journal Nature Genetics, describes the discovery of a new clue found in the blood. Although the discovery is preliminary, the team hopes to soon advance to the clinical stage where it can be tested. If the testing proceeds as hoped, it could make cancer diagnosis faster and more effective.
