Inferences Practice Test

A town compared accident rates before and after installing a new traffic light at a busy intersection. In the year after installation, reported accidents decreased by 15%. However, the town also lowered the speed limit on the surrounding road network and ran a safety campaign emphasizing seatbelt use. Notably, accidents at nearby intersections without new lights also decreased, though by a smaller amount. From the evidence, it is most reasonable to infer that _______.

Which choice most logically completes the text?

In a greenhouse experiment, tomato plants were grown under either blue-heavy LED light or red-heavy LED light. The blue-heavy group produced shorter plants with thicker stems, while the red-heavy group produced taller plants with thinner stems. Fruit yield, however, differed little between the groups, and temperature and watering were kept identical. A student concludes that red-heavy light is “better” for tomatoes because it makes plants taller. The evidence in the experiment most strongly suggests that _______.
