Question 1 of 7
Astronomer: Most stars are born in groups of thousands, each star in a group forming from the same parent cloud of gas. Each cloud has a unique, homogeneous chemical composition. Therefore, whenever two stars have the same chemical composition as each other, they must have originated from the same cloud of gas.
Which of the following, if true, would most strengthen the astronomer’s argument?CorrectIncorrect
Question 2 of 7
Candle Corporation’s television stations are likely to have more income from advertisers than previously. This is because advertisers prefer to reach people in the 18 to 49-year-old age group and the number of people in that group watching Candle television is increasing. Furthermore, among Candle viewers, the percentage of viewers 18 to 49 years old is increasing.
Which of the following, if true, would most strengthen the argument that Candle Corporation will receive more income from advertisers?CorrectIncorrect
Question 3 of 7
Editorial: The roof of Northtown’s municipal equipment-storage building collapsed under the weight of last week’s heavy snowfall. The building was constructed recently and met local building-safety codes in every particular, except that the nails used for attaching roof supports to the building’s columns were of a smaller size than the codes specify for this purpose. Clearly, this collapse exemplifies how even a single, apparently insignificant departure from safety standards can have severe consequences.
Which of the following, if true, most seriously weakens the editorial’s argument?CorrectIncorrect
Question 4 of 7
During the earliest period of industrialization in Britain, steam engines were more expensive to build and operate than either windmills or water mills, the other practicable sources of power for factories. Yet despite their significant cost disadvantage, steam-powered factories were built in large numbers well before technical improvements brought their cost down. Furthermore, they were built even in regions where geographical conditions permitted the construction of wind and water-powered factories close to major markets.
Which of the following, if true, most helps to explain the proliferation of steam-powered factories during the earliest period of industrialization in Britain?CorrectIncorrect
Question 5 of 7
Suncorp, a new corporation with limited funds, has been clearing large sections of the tropical Amazon forest for cattle ranching. This practice continues even though greater profits can be made from rubber tapping, which does not destroy the forest, than from cattle ranching, which does destroy the forest.
Which of the following, if true, most helps to explain why Suncorp has been pursuing the less profitable of the two economic activities mentioned above?CorrectIncorrect
Question 6 of 7
A newly discovered painting seems to be the work of one of two seventeenth-century artists, either the northern German Johannes Drechen or the Frenchman Louis Birelle, who sometimes painted in the same style as Drechen. Analysis of the carved picture frame, which has been identified as the painting’s original seventeenth-century frame, showed that it is made of wood found widely in northern Germany at the time, but rare in the part of France where Birelle lived. This shows that the painting is most likely the work of Drechen.
Which of the following is an assumption that the argument requires?CorrectIncorrect
Question 7 of 7
ln order to reduce the number of items damaged while in transit to customers, packaging consultants recommended that the TrueSave mail-order company increase the amount of packing material so as to fill any empty spaces in its cartons. Accordingly, TrueSave officials instructed the company’s packers to use more packing material than before, and the packers zealously acted on these instructions and used as much as they could. Nevertheless, customer reports of damaged items rose somewhat.
Which of the following, if true, most helps to explain why acting on the consultants’ recommendation failed to achieve its goal?CorrectIncorrect
