(FUVEST - 2001 - 1a fase) It is a nice irony, given that scientific genetics started with the manipulation of a crop plant, the pea, that the most vehement public opposition to it in recent years has come from those who object to the genetic manipulation of crops. At the moment, so-called genetically modified (GM) crops are in disgrace. Consumers, particularly in Europe, are wary of buying food that may contain them. Environmental activists are ripping up fields where they are being tested experimentally. And companies that design them are selling off their GM subsidiaries, or even themselves, to anyone willing to take on the risk. Yet the chances are that this is just a passing fad. No trial has shown a health risk from a commercially approved GM crop (or, more correctly, a transgenic crop, as all crop plants have been genetically modified by selective breeding since time immemorial). And while the environmental risks, such as cross-pollination with wild species and the promotion of insecticide-resistant strains of pest, look more plausible, they also look no worse than the sorts of environmental havoc wreaked by more traditional sorts of agriculture. THE ECONOMIST JULY 1ST 2000 Which of these statements is true according to the passage?

(FUVEST - 2001 - 1a fase) MICHAEL D. COES Breaking the Maya Code. Revised paperback edition. First published 1992. Thames Hudson, New York, 1999 ($18.95). The decipherment of the Maya script was, Coe states, one of the most exciting intellectual adventures of our age, on a par with the exploration of space and the discovery of the genetic code. He presents the story eloquently and in detail, with many illustrations of the mysterious Maya inscriptions and the people who tried to decipher them. Most of the credit, he says, goes to the late Yuri V. Knorosov of the Russian Institute of Ethnography, but many others participated. They did not always agree, and some of them went up blind alleys. Coe----- emeritus professor of anthropology at Yale University----- vividly describes the battles, missteps and successes. What is now established, he writes, is that the Maya writing system is a mix of logograms and syllabic signs; with the latter, they could and often did write words purely phonetically. SCIENTIFIC AMERICAN APRIL 2000 The passage tells us that Michael D. Coe
