Section 7 Cumulative Reading
Read the passage carefully. You may underline words you recognise from this lesson and earlier lessons.
A Decision About the Science Building
Riverton's school board had to decide whether to replace an aging science building or renovate it. The issue seemed simple at first, but an exhaustive engineering report revealed several complications. Some classrooms had only minor damage, while one wing showed an anomaly: cracks far larger than those found elsewhere. Engineers warned that the cumulative effect of years of moisture had weakened part of the structure.
A proponent of renovation argued that the building could still be viable if the damaged wing were reinforced. To substantiate that claim, she cited empirical test results showing that most of the foundation remained strong enough to withstand additional stress. Another board member expressed dissent and invoked a previous safety case as precedent for replacing buildings with similar problems. He argued that the magnitude of the risk warranted a more cautious approach.
The board commissioned two concurrent studies. One examined construction costs, while the other tested whether damage correlated with soil movement beneath the property. The findings were not immediately conclusive. One report used equivocal language, and several assumptions remained implicit. Rather than rush the decision, the board required a more rigorous analysis that would aggregate data from every inspection and synthesize the results into one final recommendation.
The new analysis changed the debate. It showed that the predominant problem was limited to one section and that an autonomous drainage system could prevent future moisture buildup. Replacement would still be safer in some respects, but renovation was financially viable and did not require the school to relinquish the building for two full years. After reviewing the evidence, even several original critics agreed that the revised plan could transcend the earlier disagreement. The board approved renovation, but only with stringent safety checks and an unprecedented schedule of follow-up inspections. It also required annual reviews so future structural problems could be detected before they became severe.
Section 8 Reading & Application
Answer the questions using the passage. For the written questions, reply in complete sentences on the lines provided.
1.
Why did the board hesitate to make an immediate decision after the first round of reports?
□The board had no information about construction costs.
□The school had already decided to abandon the building.
□The engineers refused to inspect the damaged wing.
□The findings were not yet clear or complete enough to settle the issue.
2.
What evidence supported the argument that renovation might be viable?
□Testing showed that most of the foundation remained strong enough to handle additional stress.
□The school had never experienced moisture problems before.
□Replacement would let students remain in the building during construction.
□Every part of the building was undamaged.
3.
What did the final analysis reveal about the building's main problem?
□The entire foundation needed replacement.
□The soil beneath every part of the building was unstable.
□The most serious problem was concentrated in one section rather than spread throughout the building.
□The damage was caused mainly by poor ventilation.
4.
Why did some original critics eventually support renovation?
5.
Describe a claim that should be supported with empirical evidence before people accept it. Explain what evidence could substantiate it.
6.
Describe a situation in which someone might express dissent because a past precedent suggests a different decision.
7.
