Read the passage and answer the question. A Garden on Cooper Street [1] Last spring, the Eastside Neighborhood Association turned an empty lot on Cooper Street into a community garden.

The writer wants to add a sentence after Sentence 3 that gives a specific example of how the garden brings neighbors together. Which choice best accomplishes this purpose?

• AA. The lot sat vacant for nearly ten years before the association signed a lease with the city.
• BB. Each Saturday morning, plot holders gather at a long table by the gate to trade seeds and share recipes.
• CC. Tomatoes, peppers, and several varieties of squash are among the crops that grow best in the garden's soil.
• DD. Gardening has become increasingly popular among city residents across the country over the past several years.

A student studied how the length of daily light exposure affects the growth of bean seedlings. Five groups of identical seedlings were grown for 14 days at the same temperature and with the same amount of water. Each group received a different number of hours of light per day. The average height of each group was then measured. Table Hours of light per day | Average height (cm) 6 | 4.2 10 | 7.5 14 | 11.1 18 | 11.3 22 | 9.0 According to the table, the greatest increase in average height occurred when the daily light exposure was increased from:

• AA. 6 hours to 10 hours.
• BB. 10 hours to 14 hours.
• CC. 14 hours to 18 hours.
• DD. 18 hours to 22 hours.

The number of native perch in Lake Harlan fell sharply over a five-year period. Two scientists offered explanations. Scientist 1: Fertilizer runoff added large amounts of phosphorus to the lake. The phosphorus caused heavy algae growth, and when the algae died and decayed, the process used up dissolved oxygen in the deeper water. The perch died from lack of oxygen. Scientist 2: Northern pike were illegally introduced to the lake. Pike are predators that feed heavily on perch, and the growing pike population consumed enough perch to cause the decline. Which of the following findings, if true, would support Scientist 1's explanation but NOT Scientist 2's explanation?

• AA. Many of the dead perch recovered from the lake bottom had no wounds, and dissolved oxygen in the deep water measured below 2 mg/L.
• BB. The number of pike captured in the lake each year rose steadily during the same five years that the perch numbers fell.
• CC. Perch remains were found in the stomachs of most of the pike netted in the lake during the final year of the study.
• DD. Perch numbers began to recover in the sections of the lake where wildlife officials had removed most of the pike.

Passages A and B are about the use of phone navigation. Passage A From an essay by Priya Nair, "Lost, and Better For It": When I unfold a paper map, I have to find myself on it. That small effort builds a picture of the town in my head. People who follow a phone's spoken directions never build that picture, and they arrive without knowing where they have been. Passage B From a research summary by Daniel Whitcomb: In a study of 80 adults, those who followed turn-by-turn voice directions recalled fewer landmarks than those who used paper maps. Adults who first studied the phone's map view for two minutes, then walked the route with the screen off, recalled as many landmarks as the paper-map group. Which of the following statements is the one Whitcomb would most likely make about Nair's claim that phone users never build a mental picture of a town?

• AA. The claim is too broad, because the weaker recall appeared with voice directions but not when the map view was studied first.
• BB. The claim is untestable, because the study measured landmark recall rather than how well participants knew the town.
• CC. The claim is correct, because phone users recalled fewer landmarks than paper-map users in every group studied.
• DD. The claim is incorrect, because voice directions led to better recall of landmarks than paper maps did.
