Making Inferences Practice Test

During the winter exams, the proctor noticed that Lina sharpened her pencil only once, yet she kept turning it in her fingers as if measuring its length. Her answers were neither hurried nor hesitant, but she paused before each new section to read the directions twice, lips moving silently. When another student’s calculator beeped, Lina flinched, then pressed her palm flat on the desk until the knuckles whitened. After the exam, she did not compare responses with friends; instead, she walked directly to the guidance office and asked whether “scores are ever corrected after they’re posted.” The counselor, attempting reassurance, mentioned that Lina’s average was already high; Lina responded, “High isn’t the same as safe,” and asked when the next retake window opened. In the waiting area, she unfolded a letter with a university crest, but the page she reread was the financial aid schedule, not the congratulatory paragraph. Based on the passage, why might Lina be unusually concerned about minor exam details?

In 1967, engineers at the Kestrel Dam installed a new set of gates designed to “moderate seasonal surges,” according to a plaque that emphasized safety and modernity. Yet the maintenance logs, kept in a narrow ledger room that smelled of oil and damp concrete, recorded a different preoccupation: repeated notes about “unexpected silt load,” “turbidity spikes,” and “downstream complaints.” A supervisor’s memo dated 14 June instructed crews to schedule gate tests “only after dusk,” and to notify the local radio station using the phrase “routine calibration,” regardless of actual discharge volume. In late July, fishermen gathered near the spillway reported that the river ran “the color of tea” for two days, after which the water cleared and the fish returned, but smaller than before. The town council minutes from 2 August mentioned a “temporary reduction in reservoir recreation permits,” though no explanation was provided, and the same meeting approved funds for repainting picnic tables. A visiting hydrologist, asked about the dam’s performance, remarked that “systems are often judged by what they hide, not what they release,” and declined to be quoted by name. The passage suggests that the dam’s new gates were used in part to address what issue?
