Function of a Word or Phrase Practice Test

Which choice best describes the function of the underlined sentence in the overall structure of the text?

Some educators advocate for frequent low-stakes quizzes as a way to improve long-term learning. Studies of retrieval practice show that recalling information strengthens memory more effectively than rereading notes, even when students feel less confident afterward. In classroom trials, students who took short quizzes often performed better on cumulative exams than students who spent the same time reviewing. However, quizzes can crowd out discussion or project work if they are overused or poorly aligned with course goals. Therefore, proponents typically recommend brief quizzes integrated into broader instructional plans.

Urban ecologists have argued that city parks can serve as “stepping-stones” for pollinators moving across heavily built landscapes. To test this idea, researchers surveyed bee species in 18 parks that varied in size and distance from one another. They found that parks closer together shared more species, suggesting that bees disperse between green spaces rather than persisting in isolation. However, the study also noted that floral diversity within each park predicted bee abundance more strongly than park size did. Taken together, the results imply that connectivity matters, but only when parks also provide sufficient food resources.
