Interpretação de Texto - UNIRIO

Research shows that sunscreens may not be as effective as hoped at preventing sunburn. Users may be spending long hours in the sun with a false sense of security, and though lotions may protect against sunburning UVB rays, it does little to block out the potentially more dangerous UVA rays. Another worry is the long-term effects of the chemicals contained in the suntan lotion themselves. To make spending time outdoors safer, a company called Frogskin, Inc., located in Scottsdale, Arizona, is marketing a line of clothing called Frogware that, wet or dry, protects the user from the damaging effects of the sun more effectively than sunscreens.

"Our T-shirts give you the same amount of protection from the sun that a heavy sweat shirt would", says Jan Steinberg, president of Frogskin. "But who wants to wear a sweat shirt in the water?" A typical cotton T-shirt, for instance, has a sun protection factor (SPF) of 5; a Frogskin T-shirt has a SPF of 30. Frogwear, says the maker, blocks out 98.5% of all UVB rays and 97% of all UVA rays. The fabric, which is lighter than cotton but more durable, also helps keep you cool, by wicking perspiration away from the skinIn addition, Frogwear absorbs very little water when wet and dries quickly. Prices range from $ 18 for a hat to $ 50 for a sports jacket.

1. According to the text, why is it not totally safe to wear lotions to prevent sunburn?

a) First because they only block the UVA rays; second, the chemicals in the lotions may be harmful after a while.
b) Not only do they fail to block out UVB rays, but produce chemical reactions in the long-run.
c) Besides blocking out only one type of UV rays, the lotions contain substances that may be harmful after a long period of use.
d) Besides blocking out all UVB and UVA rays, they prevent the action of damaging substances after a while.
e) While they fail to protect against the dangerous UVA rays, they protect against other substances after a long period of use.

Resposta correta: c

Resolução: O texto afirma o seguinte: “it does little to block out the potentially more dangerous UVA rays. Another worry is the long-term effects of the chemicals contained in the suntan lotion themselves”. (faz pouco para bloquear os raios UVA que são potencialmente mais perigosos. Outra preocupação é os efeitos a longo prazo dos produtos químicos contidos na própria loção bronzeadora).

A resposta correta é, portanto, a alternativa c: além de bloquear apenas um tipo de raio UV, as loções contêm substâncias que podem ser prejudicais a longo prazo.

b) it is light; furthermore, it has a SPF of 30.
c) it lasts longer than a sweat shirt in the water.
d) it blocks perspiration out of the body.
e) people want to wear light sweat shirts in the water.

Resposta correta: b

Resolução: O texto informa o seguinte a respeito da Frogwear: tem um SPF de 30, é mais leve e dura mais do que o algodão. A resposta correta é, portanto, a alternativa b: it is light (é leve), furthermore, it has a SPF of 30 (além disso, tem um SPF de 30).
