Rearrange the letters given below to form the name of a weapon: REPSA

Correct — B.
Rule: the word must use every letter of REPSA once and name what the stem asks for, a weapon.

REPSA holds A, E, P, R and S.

Spear uses exactly those five letters and is a weapon with a long shaft and a pointed head → option (b).

Why the others are wrong

• (a)
  parse — Parse uses the same five letters, but it is a verb meaning to break a sentence into its grammatical parts. It names no weapon.
• (c)
  spare — Spare uses the same five letters, but it means extra or kept in reserve, as in a spare tyre. It names no weapon.
• (d)
  asper — Asper uses the same five letters, but it is the name of an old Turkish coin, not a weapon.

A word-formation question has two filters: the letters, then the meaning.

Here the letter filter removes nothing. Parse, spear, spare and asper are all exact rearrangements of REPSA, so counting letters cannot decide.

The decision rests on the category word in the stem, weapon, and spear is the option that names one.

Key facts

• REPSA contains the letters A, E, P, R and S, one each.
• Parse, spear, spare and asper are all anagrams of REPSA.
• A spear is a weapon with a long shaft and a pointed tip, thrown or thrust.

Common traps

• Stopping at the letter check: all four options pass it, so it proves nothing here.
• Choosing spare or parse because they are more familiar words, without testing them against 'weapon'.
