Explanation
Correct answer: C.
Choice C is the best answer because it most effectively uses data from the table to complete the text’s comparison of the studies about food choices. The table shows information from four studies about food choices, including each study’s location, the context of the food choices examined, the study population, and the number of participants. According to the table, the study with the greatest number of participants (142) was conducted in Ghana and Kenya and involved only adolescents.
Why the other choices are wrong
Choice A
Choice A is incorrect because the table indicates that the study that involved only children was conducted in the United States and had 44 participants—not the greatest number of participants. According to the table, the study with the greatest number of participants (142) involved only adolescents.
Choice B
Choice B is incorrect because the table indicates that the study population that consisted of both adolescents and adults was the India study, which had 94 participants—not the greatest number of participants. According to the table, the study with the greatest number of participants (142) involved only adolescents.
Choice D
Choice D is incorrect because, according to the table and the text, the study that involved only adults was conducted in Canada and had 17 participants—the smallest, not the greatest, number of participants in the table.
