Passage I
A study was conducted to examine whether female Blattella germanica (a species of cockroach) prefer to eat cat food, cheese, ham, or peanuts. First, 200 mg of each of the 4 foods was separately placed into a single box. Then, adult female B. germanica were added to the box. Figure 1 shows how the mass, in mg, of each food in the box changed over time after the addition of the B. germanica. Table 1 shows the percent by mass of carbohydrates, lipids, proteins, and water, respectively, present in each of the 4 foods tested in the study.

Correct Answer is A
Explanation
Looking at figure 1, the remaining amount of cat food is more than that of ham, which means that B. germanica eats less cat food
