Read the passage below about cold-weather equipment maintenance:
During operations in sub-zero climates, standard engine oil thickens into a sluggish paste, preventing rapid lubrication of moving parts at ignition. At the same time, the chemical reactions inside vehicle batteries slow down drastically, cutting the electrical current required to turn the starter motor. To combat these issues, maintenance technicians equip vehicles with electric block heaters and thermal battery wraps prior to winter deployments.
Based on the details provided, complete the summary sentence below with the words that best capture the author's implicit main idea.
Answer:The author's unstated central claim is that extreme cold impairs vital vehicle systems, requiring specialized thermal equipment to prevent mechanical 【damage】 and ensure dependable 【starting】.
Answer
Blank 1: damage (or wear / failure); Blank 2: starting (or startup / operation / ignition / readiness)
The passage details how freezing temperatures compromise both lubrication and battery power, and how heaters and thermal wraps counter these effects. Combining these supporting facts leads to the implied main idea: specialized heating equipment prevents mechanical damage and ensures reliable starting.
