Read the passage below. Based on the passage, complete the statement that encapsulates the implicit main idea.
Cevap:Before machining high-precision engine components, technicians allow raw metal stock and measuring gauges to rest together in the calibration room for several hours. Measuring metal parts immediately after bringing them in from a cold outdoor loading dock produces inconsistent readings. In addition, holding a steel micrometer in a warm hand for too long transfers body warmth and alters readings by thousandths of an inch. Microscopic dimensional changes can easily compromise tightly fitted mechanical assemblies.
The unstated central point of the passage is that 【temperature】 must be carefully controlled to achieve reliable precision measurements.
The unstated central point of the passage is that 【temperature】 must be carefully controlled to achieve reliable precision measurements.
Cevap
temperature (or temperature variations / thermal conditions)
The correct answer identifies temperature (or thermal conditions) because every sentence in the passage provides a specific scenario where heat or cold alters physical dimensions and disrupts precision measurements.
