Very few insects are as busy as a bee. The correct comparative form of the sentence is-

Correct Answer: (C) A bee is busier than most other insects. Degree transformation — converting Positive degree to Comparative degree — is one of the most frequently tested grammar skills in NTRCA College Level exams. The Three Degrees of Comparison: — Positive: "Very few insects are as busy as a bee." — Comparative: "A bee is busier than most other insects." — Superlative: "A bee is one of the busiest insects." The Key Rule for Positive → Comparative Transformation: When the Positive degree uses "very few...as...as", the Comparative equivalent is: "Subject + comparative adjective + than + most other + noun." Why (C) is correct: "Very few insects are as busy as a bee" → means almost all insects are LESS busy than a bee → So a bee is busier than MOST OTHER insects. ✓ "A bee is busier than most other insects." Why others are wrong: ✗ (A) "busier than very few insects" — this would mean most insects ARE as busy or busier, which is the OPPOSITE meaning. ✗ (B) "busier than few insects" — "few" without "most other" distorts the scope; grammatically weak. ✗ (D) "more busy" — incorrect comparative form; the correct form of "busy" is "busier" (not "more busy"). Spelling/Form Reminder: busy → busier (NOT "more busy") — one-syllable and two-syllable adjectives ending in -y take -er/-est. Transformation Rule Summary: Positive: "Very few X are as [adj] as Y." Comparative: "Y is [adj]-er than most other X." Superlative: "Y is one of the [adj]-est X." Source: English Grammar — Wren & Martin; Sentence Transformation Practice; NTRCA Question Bank.
