To determine whether chimpanzees are more likely to delay gratification for a cooked
food reward than they are for a raw food reward, cognition researchers Felix Warneken
and Alexandra Rosati conducted an experiment comparing chimpanzees' decisions [1]
in two situations: a "raw-delay" condition and a "cooked-delay" condition. In the raw-
delay condition, Warneken and Rosati offered the chimpanzees a choice between
receiving a piece of raw food immediately and waiting for one minute to receive three
pieces of raw food; the chimpanzees chose the larger, delayed reward 60 percent of the
time. In the cooked-delay condition, in which the chimpanzees could receive one piece
of raw food immediately or wait one minute for three pieces of cooked food, they chose
the larger, delayed reward approximately 85 percent of the time.

Looming above passersby in Lisbon, Portugal, a gigantic raccoon protrudes from the
side of a building. A close look at this multimedia street sculpture reveals that the
raccoon's eyes are made from discarded tires, its arms from dented bumpers, and its
claws from assorted metal scraps. This larger-than-life 3-D street mural is the creation
of Artur Bordalo, a Portuguese artist whose unusual animal sculptures made out of
garbage are attracting international attention. That's exactly what Bordalo [1] wants. His
goal is to: raise awareness about the destructive effects of excess consumerism. To
that end, the broad appeal of the animal world serves Bordalo's purpose well. After the
spectacle of the towering raccoon captures the interest of passersby, the sculpture's
materials demand that viewers confront the waste products that are harming the natural
world.
Hint: A colon can be used to introduce an example or elaboration.

This passage is adapted from Fyodor Dostoevsky, The Brothers Karamazov originally
published in 1880.
Alyosha had been struck by Katerina Ivanovna's beauty when, three weeks before,
Dmitri had first brought him, at Katerina Ivanovna's special request, to be introduced to
her. There had been no conversation between them at that interview, however.
Supposing Alyosha to be very shy, Katerina Ivanovna had talked all the time to Dmitri to
spare him. Alyosha had been silent, but he had seen a great deal very clearly. He was
struck by the imperiousness, proud ease, and self-confidence of the haughty girl. And
all that was certain, Alyosha felt that he was not exaggerating it. He thought her great
glowing black eyes were very fine, especially with her pale, even rather sallow, longish
face. But in those eyes and in the lines of her exquisite lips there was something with
which his brother might well be passionately in love, but which perhaps could not be
loved for long. He expressed this thought almost plainly to Dmitri when, after the visit,
his brother besought and insisted that he should not conceal his impressions on seeing
his betrothed.
"You'll be very happy with her, but perhaps—not tranquilly happy."
"Quite so, brother. Such people remain always the same. They don't yield to fate. So
you think I shan't love her for ever."
"No; perhaps you will love her for ever. But perhaps you won't always be happy with
her."
Alyosha had given his opinion at the time, blushing, and angry with himself for having
yielded to his brother's entreaties and put such "foolish" ideas into words. For his
opinion had struck him as awfully foolish immediately after he had uttered it. He felt
ashamed too of having given so confident an opinion about a woman.
Which choice provides the best evidence for the idea that Alyosha does not have much
experience with women?
HINT—Consider which lines reveal details about Alyosha that indicate lack of certainty.
a. Lines beginning--"Supposing . . . him."
b. Lines beginning "He was . . . girl."
c. Lines beginning "Aloysha . . . words."
d. Lines beginning "He . . . woman." - Answer d. Lines beginning "He . . . woman."
A survey of a random sample of 12,000 adults in the US home-buying market finds that
97% of those surveyed recognized a certain real estate brand name. If the margin of
error was 2.4%, of the following, which is the best estimate of the percent of adults in
the home-buying market in the US who recognize this real estate brand name?
HINT--
If the researchers repeated the study many times with randomly selected groups of US
adult participants, they would expect the percent of adults in the home-buying market
who recognize the brand name to be within the interval created by the sample
proportion, plus or minus the margin of error.
