An environmentalist delivered a speech about how young people are unwilling to conserve natural resources. Which sentence in the passage contains the persuasive technique of expert opinion?
Teens and Conversion Trends
An Inconvenient Truth, Al Gore's movie on global warming, is now the fourth highest-grossing documentary of all time. But apparently, it isn't young adults who are paying the price of the ticket or, more important, taking the truth about the environment to heart.

In fact, the inconvenient truth today is that youths' willingness to conserve gas, heat, and energy has taken a steep plunge since the 1980s. According to data from Monitoring the Future, a federally funded national survey on trends in the attitudes, values, and behavior of high school seniors since 1976, there has been a clear decline in conservation behavior among 18-year-olds over the past 27 years; although, we are not yet sure whether these attitudes follow youths into adulthood. One of every fifteen teens participates in conservation. Compare that to one in five during the 1970s. This decline, interestingly, is coupled with a rise in materialistic values.

In fact, trends in materialism and conservation are highly related. At times when youths place higher value on material goods, they are also much less likely to say they would conserve resources. And when youths are more materially driven, they are also less likely to believe that natural resources will become scarce in the future. Since the 1990s, the trends in materialism seem to have topped out at a steady high level. The willingness to conserve keeps declining. These opposing values should raise a red flag about the consumer culture and its influence on youth.

i think the answer is b

in the short story the slip-over sweater by jesse stuart, the main character and narrator shan is friends with grace, an intelligent girl he has known since childhood and with whom he used to be in love.

at the beginning of the story, shan believes he’s no longer in love with grace, but loves jo-anne instead. in order to buy a slip-over sweater and have jo-anne wear it so that the other students would know she loved him too, shan takes a loan at the bank.

while jo-anne is wearing shan’s sweater, his friend grace starts to wear another popular boy’s one, roy’s sweater. because of that, the other students begin to pay attention to grace and compliment her perseverance and effort. they admire her for walking 5 miles to school every day, despite the weather, and still getting the best grades. shan, who knows all of that for a fact, says, as the narrator, ‘and i knew she had the durability and the toughness of a storm-battered mountain oak.’ he compares his friend’s strength – not only physical, but also of character – to an oak tree, whose wood is known for being sturdy.

as the story goes on, shan changes his behavior out of concern for the debt he has to pay at the bank. his new girlfriend jo-anne never asks him what is wrong nor offers any sort of . instead, she breaks up with shan for not being as fun as she thought he was supposed to be. grace, however, not only asks about shan’s problem, but him make the money he needs. shan can’t but notice how different the girls are and what a wonderful person grace is.   even though he used to find jo-anne prettier at the beginning of the story, he now says, ‘grace was as beautiful as our mountain was in april, prettier than a blossom of wild phlox or a mountain daisy.’ his comparing grace to a mountain or something that exists on a mountain (such as a mountain oak or daisy) certainly has important meaning since shan loves the mountain and everything about it and he knows the mountain thoroughly. shan also loves and knows grace as completely as he does the mountain.

i believe that the correct answer is (d) the struggle between tradition and change.
