Question

If error is a , fault is .

• A. defect - a mistake
• B. mistake - a defect
• C. slip - an inaccuracy
• D. blunder - to blame

Hint:

Think about which word means a one-time slip and which means a lasting flaw.

Answer 1

The Correct Option is B

This sentence compares two close but different words, error and fault, so the correct pair must capture their true difference.

1. defect - a mistake: This flips the meaning. A defect suits fault, not error, so the order here is backwards.
2. mistake - a defect: An error is a mistake anyone can make once, and a fault is a defect that repeats or runs deeper. This pair matches both blanks in the right order.
3. slip - an inaccuracy: A slip is close to error, but an inaccuracy does not carry the sense of a lasting flaw that fault needs here.
4. blunder - to blame: A blunder is a bigger careless mistake, and "to blame" is not even a matching noun phrase for the blank.

Option B keeps the logic straight: error means a mistake, fault means a defect. So option B is correct.

Let's summarize:

• Error is a passing mistake.
• Fault is a lasting defect or flaw.

Read both blanks as one unit, not separately, and the intended contrast becomes clear.
