Reаd the fоllоwing pаssаge and select the best answer In July and August, here оn the high desert, come the thunderstorms. The mornings begin clear and dazzling bright, the sky as blue as the Virgin’s cloak, unflawed by a trace of cloud. By now, though, the clouds are beginning to form over the distant mountains, coming, it seems out of nowhere, out of nothing, a special creation. They merge and multiply, piling up like whipped cream, like mashed potatoes, like seafoam, building upon one another into a second mountain range greater in size than the earthly range below. The massive forms jostle and grate, and the sound of thunder is heard on the sun-drenched land. More clouds emerge from empty sky, anvil-headed giants with glints of lightning in their depths. An armada forms, advances, floating on a plane of air that makes it appear, from below, as a fleet of ships must appear to the fishes of the sea.

Directiоns: Chооse the аppropriаte letter to indicаte the conclusion that can be drawn from each passage. In July of 2010, Courtney Purvin was stunned by a suggestion on her Facebook page. The site was suggesting that she get back in touch with an old family friend. What shocked Ms. Purvin was the total impossibility of following up on this idea. The friend mentioned had died almost three months before. When Facebook first made its debut, such depressing surprises rarely occurred. Users were in their teens and twenties. Death was an infrequent visitor. But when the site was opened up to people of all ages, it became all too possible that someone who signed up could pass away. Meanwhile Facebook’s software would keep churning out suggestions that former friends might like to get in touch with the deceased. As Meredith Chin, a Facebook spokeswoman put it, the site is huge “and with people passing away every day, we’re never going to be perfect at catching it [the suggestion about connecting with someone deceased].” This is a problem that is not likely to go away anytime soon since people over the age of 65 are signing up for Facebook at a faster rate than any other age group.
