Inferences Practice Test

In a school cafeteria, staff tested two changes to reduce food waste over four weeks. In weeks 1–2, they kept the menu the same but moved fruit to the start of the serving line; fruit taken increased by 30%, yet total waste stayed about the same. In weeks 3–4, they kept fruit at the start and also reduced portion sizes for pasta by 15%; total waste dropped by 18%, while fruit taken remained high. Because the menu itself did not change across the four weeks, the most logical inference is that _______. Which choice most logically completes the text?

A city planted trees along two similar streets to reduce summer sidewalk temperatures. On Street A, trees were planted on both sides; average midday sidewalk temperature fell by $2.5^\circ\text{C}$ the next summer. On Street B, trees were planted on one side only; temperature fell by $1.0^\circ\text{C}$. However, the next summer was also slightly cooler citywide, with a $0.7^\circ\text{C}$ drop in average midday air temperature. Given these observations, it is most reasonable to infer that _______.
