Reflective Pavement Pilot: Reading Inference Under Time Pressure
During a timed reading section, a candidate has 12 minutes for a 180-word passage and three questions. The passage states: "In 2023, a desert city tested reflective pavement on 3.2 km of residential streets. Summer surface temperatures fell by up to 11°C, but afternoon air temperature changed by less than 0.5°C. Residents reported more glare, and maintenance costs rose 18%. The city extended the pilot to two blocks near a school but not to the downtown corridor, where shade trees already cover 40% of sidewalks." The candidate's first answer says the pilot "failed to reduce heat." The second says the city extended the pilot because residents demanded it. The third asks what "corridor" most nearly means. The candidate has flagged the phrase "but not to the downtown corridor" as confusing.
1. Evaluate the candidate's first answer: "The pilot failed to reduce heat." Is it supported by the passage? Explain what evidence would make a better answer.

The answer is too strong. The passage reports two different measures: surface temperature fell by up to 11°C, while afternoon air temperature changed by less than 0.5°C. A 0.5°C change is small, but the passage does not say the pilot's goal was to lower air temperature, nor does it give a failure threshold. "Failed to reduce heat" ignores the large surface-temperature result and treats one limited metric as the whole outcome. A better answer would say the pilot reduced surface heat but had little measured effect on afternoon air temperature, and would note that the passage does not establish overall success or failure.
2. The candidate's second answer claims the city extended the pilot because residents demanded it. Using the passage, explain why this is a weak inference.

The passage gives a different reason for the extension pattern. It says the city extended the pilot to two blocks near a school but not to the downtown corridor, where shade trees already cover 40% of sidewalks. That contrast suggests siting was influenced by existing shade: downtown already had tree cover, so reflective pavement was less necessary there. Resident glare complaints could support caution, not expansion. The candidate has confused a possible public concern with the stated basis for extension. A defensible inference is that the city targeted areas with less shade, not that resident demand caused the extension.
3. What does "corridor" most nearly mean in "the downtown corridor, where shade trees already cover 40% of sidewalks"? Show how context narrows the meaning.

In this context, "corridor" means a main route or linear stretch of roadway in a downtown area, not a hallway inside a building. Three clues narrow it. First, it contrasts with "residential streets," so it is an urban street category. Second, it is modified by "where shade trees already cover 40% of sidewalks," which describes an outdoor streetscape. Third, the passage's planning register uses "corridor" for a road or transit route. The safest answer is "a main road or route," supported by the street-and-sidewalk context rather than by the word's other common meaning.
