Question 1

Consider this passage. "Astrophysicist Elena Vance measured the width of the spectral lines coming from two dozen star clusters and found that the lines were consistently broader in the clusters where earlier surveys had recorded denser surrounding gas. Vance notes that no other property she measured varied with line width. This suggests that ______" Which choice most logically completes the writer's statement?

Accepted Answer

the density of the surrounding gas is associated with how broad the spectral lines of these clusters appear.

Answer

every star cluster in the universe that is surrounded by dense gas produces broad spectral lines.

Answer

broad spectral lines cause the gas around a star cluster to grow denser over time.

Answer

the clusters Vance studied have broader spectral lines than the clusters she did not study.

Question 2

Consider this passage. "Biologist Sarah Jenkins observed that the Northwood warbler, whose diet consists almost entirely of forest beetles, shifted its migration route westward only in the years when the local beetle population fell by more than forty percent. This suggests that ______" Which choice most logically completes the writer's statement?

Accepted Answer

the availability of the warbler's principal food may be one factor in where it migrates.

Answer

the Northwood warbler is unable to migrate eastward under any conditions.

Answer

the decline of forest beetles is the only thing that affects where the Northwood warbler migrates.

Answer

the Northwood warbler's own population grows in the years when the beetle population falls.

Question 3

Consider this passage. "Marine researcher David Wu found that corals in the Azure Trench grew faster in places where the water temperature stayed stable, and that this held regardless of the depth at which the corals were growing. This suggests that ______" Which choice most logically completes the writer's statement?

Accepted Answer

temperature stability is a factor in how fast corals grow in the Azure Trench.

Answer

deeper water is always harmful to coral growth in the Azure Trench.

Answer

corals in the Azure Trench grow faster in shallow water than in deep water.

Answer

water temperature is the only variable affecting coral growth anywhere in the world.

Question 4

Consider this passage. "Sociologist Elena Rossi studied work and home life in one city and found that employees working remotely reported higher job satisfaction than those in traditional offices, but only among employees whose commute had previously run to more than an hour. This suggests that ______" Which choice most logically completes the writer's statement?

Answer

remote work is superior to office work for employees generally.

Answer

commute time is the only thing that determines job satisfaction in cities.

Answer

office employees are by their nature less satisfied than remote employees.

Answer

the effect of remote work on job satisfaction may be tied to the removal of a long commute.

Question 5

Consider this passage. "Economist Julian Vane observed that small businesses in the northern district reported rising revenue in the two years after the local government introduced a tax incentive for sustainable energy upgrades. This suggests that ______" Which choice most logically completes the writer's statement?

Answer

every small business in the northern district took up the sustainable energy upgrades.

Answer

the tax incentive may have had a positive effect on the revenue of small businesses in the district.

Answer

sustainable energy upgrades are the main driver of revenue growth for businesses everywhere.

Answer

the local government introduced the incentive in order to increase its own tax revenue.
