Experience the Quality With Free CAST Exam Questions That Helps Candidates Pass

Reading Comprehension items ask you to identify the author’s central claim and distinguish it from supporting details. The passage begins by asserting that preventive maintenance reduces unplanned outages by acting before failure. It contrasts this with deferred maintenance, which may look cheaper short-term but ultimately raises lifecycle costs due to collateral damage and overtime. The final sentence lists planning considerations—criticality, lead time, and staffing—as relevant factors, but they are supporting details, not the thesis. Option B correctly summarizes: preventive maintenance reduces unplanned outages and, considering lifecycle effects, is cost-effective overall. Option A contradicts the passage, which warns that deferral increases costs. Option C elevates one factor (technician availability) to the main point, which the passage does not do. Option D similarly overemphasizes parts lead time over criticality; the author mentions both among several considerations. The CAST requires extracting the gist and resisting distractors that focus on secondary details or oversimplify nuanced points.

Area = ½ × base × height = 0.5 × 16 × 9 = 72 ft². Correct answer is B, not D. CAST Graphic Arithmetic requires careful substitution into formulas.

A transformer can step voltage up or down. In power transmission, step-up transformers increase voltage to reduce current and minimize energy loss. Option B is correct. CAST Mechanical Concepts test electrical fundamentals.

The passage emphasizes the importance of stable foundations and inspections to prevent scaffold collapse. Option B is correct. CAST Reading Comprehension items test understanding of safety practices.

Mechanical advantage = 4. Effort = Load ÷ MA = 1,000 ÷ 4 = 250 lb. Option C is correct. CAST Mechanical Concepts frequently test pulley systems and mechanical advantage.
