Genetically modified foods
Genetically modified (GM) foods are foods derived from organisms whose genetic material (DNA) has been modified in a way that does not occur naturally, e.g. through the introduction of a gene from a different organism. Currently available GM foods stem mostly from plants, but in the future foods derived from GM microorganisms or GM animals are likely to be introduced on the market. Most existing genetically modified crops have been developed to improve yield, through the introduction of resistance to plant diseases or of increased tolerance of herbicides.

In the future, genetic modification could be aimed at
altering the nutrient content of food, reducing its allergenic
potential, or improving the efficiency of food production
systems. All GM foods should be assessed before being
allowed on the market. FAO/WHO Codex guidelines exist
for risk analysis of GM food.

01. QUESTÃO - According to the text, genetically modified foods
(A) have their natural DNA altered by a gene of a different organism.
(B) are so widespread that they may be considered naturally occurring.
(C) are healthier although they don’t taste as good as nonGM foods.
(D) comprise mostly vegetables because GM animal products are banned.
(E) are mostly rejected after the FAO/WHO assessment.
02. QUESTÃO - De acordo com o texto, uma das vantagens dos produtos agrícolas geneticamente modificados existentes é que
esses produtos
(A) se caracterizam por uma aparência padronizada.
(B) alteram o DNA de pragas resistentes a herbicidas.
(C) aumentam a tolerância a alergias.
(D) possibilitam variação ilimitada das espécies.
(E) oferecem maior produtividade.
03. QUESTÃO - No trecho final do primeiro parágrafo “through the introduction of resistance to plant diseases”, o termo em destaque equivale, em português, a
(A) embora.
(B) por meio de.
(C) durante.
(D) dentre.
(E) também.
04. QUESTÃO - No trecho do segundo parágrafo “All GM foods should be
assessed before being allowed on the market.”, o termo
em destaque pode ser corretamente substituído, sem
alteração de sentido, por
(A) could.
(B) has to.
(C) might.
(D) ought to.
(E) used to.
01. QUESTÃO - A
De acordo com o texto os alimentos geneticamente
modificados tem seu DNA natural alterado por um
gene de um organismo diferente.
Lê-se no texto:
“Genetically modified (GM) foods are foods derived
from organisms whose genetic material (DNA) has
been modified in a way that does not occur naturally,
e.g. through the introduction of a gene from a different
organism.”
02. QUESTÃO - E
Esses produtos agrícolas geneticamente modificados
oferecem maior produtividade.
Lê-se no texto:
“Most existing genetically modified crops have been
developed to improve yield, through the introduction
of resistance to plant diseases or of increased tolerance
of herbicides.”
*Yield = produtividade
03. QUESTÃO - B
Through no trecho mencionado equivale, em
português, a por meio de.
04. QUESTÃO - D
O modal should tem como substituto ought to
(=deveria).
