Answer
Correct Answer: Two
Explanation
Introduction / Context:We must count standard English words (no abbreviations) that can be formed using all letters E, P, R, O exactly once each.
Given Data / Assumptions:
- Letters: E, P, R, O.
- Every valid word must be 4 letters long and use each letter once.
- Exclude abbreviations like “repo” (database jargon) if not treated as standard lexical entries in such tests.
Concept / Approach:Enumerate common anagrams and filter to standard words.
Step-by-Step Solution:
Possible anagrams include: ROPE, PORE, REPO, POER, OPER, OEPR, etc.Recognized common words: ROPE, PORE.Ambiguous/abbrev.: REPO (treated as abbreviation), OPER/POER (not standard words).Verification / Alternative check:Cross-check both “ROPE” and “PORE” as widely accepted in basic vocabulary lists; others are either misspellings or abbreviations.
Why Other Options Are Wrong:
- None/One: Under-counts; there are at least two.
- Three: Over-counts by including an abbreviation or non-word.
Common Pitfalls:Counting “REPO” as a dictionary headword rather than an abbreviation in reasoning test norms.
Final Answer:Two
