What is the main idea of the passage?

Clear repair records turn individual experience into reliable knowledge for future workers. (Every paragraph develops how accurate records preserve observations, tests, uncertainty, and outcomes so another worker can continue from evidence.)

Why should a failed repair be included in the log?

It can rule out a possible cause or approach for the next worker. (The passage says failure narrows the field of possible causes, so the unsuccessful attempt still reduces what a later worker must consider.)

In this context, what does “diagnosis” mean?

A judgment about the cause of a problem (The log lets a worker question an earlier diagnosis, meaning the earlier judgment about what caused the machine's problem.)

Which information does the passage say useful notes should record?

What was noticed, tested, changed, and returned to service (The second paragraph explicitly lists observations, tests, changes, and whether the machine returned to service.)

A Note for the Next Pair of Hands: Level 5 Reading Comprehension Questions

A repair log is a conversation between people who may never meet. When a pump, kiln, or delivery cart fails, the person fixing it sees only the present symptom. A clear record can reveal that the same rattle appeared twice before, that one replacement part wore quickly, or that a temporary adjustment was never meant to last.

Useful notes separate observation from conclusion. They record what the worker noticed, what was tested, what changed, and whether the machine returned to service. This structure matters because confident guesses can harden into false history. It also lets the next worker avoid repeating a harmless test while still questioning an earlier diagnosis.

The best log does not try to display its writer's cleverness. It names part numbers carefully, uses plain descriptions, and marks uncertainty where uncertainty remains. Photos or diagrams can help, but only if another person can connect them to the written sequence. Even a failed repair belongs in the record, since failure narrows the field of possible causes.

Such documentation takes time during a busy shift, and its value often appears later. The writer gives up a few minutes so an unknown colleague can begin with evidence instead of rumor. In that sense, maintenance records do more than protect equipment. They turn private experience into shared memory and make careful work possible across years.
