Scientists want to study Jupiter because the planet may hold clues about the formation of the solar system. According to Scott Bolton, an astrophysicist at the Southwest Research Institute in Texas, Jupiter is like a time capsule. Many astronomers theorize that Jupiter was the first planet in the solar system to form. They believe that Jupiter got most of the mass that remained after the sun's creation, and its enormous gravity field has enabled it to hold on to that original material. Astronomers also believe that this is why the planet is so immense. Jupiter is so big that it could contain everything in the solar system, minus the sun.

Recognizing Bryant's growing fame there, the shoe company uses his image widely in its Chinese advertisements and stores. Bryant's relationship with China has also encouraged the company to fund cross-cultural exchanges. For years, it has paid for language, cooking, and martial arts workshops at schools and community centers. Bryant is featured at the sessions. In February 2011, the shoe company even paid for ten Chinese middle school students to visit the United States.

Between 1827 and 1838, John James Audubon embarked on an odyssey across America, illustrating indigenous birds with vibrant watercolors. People paid to receive a set of five life-size prints every month or two. Each delivery typically comprised one large, arresting bird—such as the hot-pink roseate spoonbill—along with four other species of more modest plumage. In sum, Audubon authored some 87 sets, totaling 435 unique illustrations. The Academy of Natural Sciences in Philadelphia had the remarkable collection bound into an enormous book now available for public viewing.


The collection _________ the variety of the native population.


A illuminates
B embellishes
C safeguards
D complements

Americans are increasingly grabbing fast food for quick and easy meals. Wary of increasing obesity, officials are trying to encourage the public to be more health conscious. They have passed legislation requiring restaurants to post nutritional information on their menus. However, these efforts do not seem to have made much difference. According to a recent study, even when such information was made available, a majority of patrons ignored it. Most people ordered whatever they wanted without giving much thought to the nutritional value of their meals.



Patrons found the information to be _________.


A educational
B irrelevant
C predictable
D perplexing
