The correct answer is a.

Complete sentence: He bought a ewe from the farmer.

Explanation:

• When a word starts with e, eu, or ew and is pronounced with a "yoo" sound (like ew in ewe), it is treated as a consonant sound for the purpose of the article. Hence, we use a, not an.

Examples:

• He is a university student.

• He is a European.

• They have a ewe.

Exception: If the "u" or initial vowel is pronounced like "uh" (short vowel sound), we use an:

• She is an unknown woman.

• The crow is an ugly bird.

The correct answer is - খ) leave

• Complete Sentence: You had better leave now.

• Rule:

  • After expressions like had better, had rather, had sooner, would rather/would sooner, rather than/sooner, as soon, infinitive (to) is not used.

    • Example: You had better start at once (not to start).

• Infinitive Forms:

  1. To-infinitive: to + verb → e.g., to go, to eat

  2. Bare infinitive: verb without to → e.g., go, eat

• Bare Infinitive Usage:
  (a) After modal verbs: can, do, may, must, shall, will, would, have, should
  - I may help you.
  - He must do it.
  (b) Auxiliary use of need and dare:
  - I dared not wake him.
  - They need not do anything.
  - Affirmative: I need to buy a pen.
  (c) After verbs like please, see, know, hear, bid, feel, let, make, watch:
  - I saw him go.
  - Passive: He was seen to go.
  (d) After had better, had rather, had sooner, would rather/would sooner:
  - You had better start at once (to start নয়)।
  (e) After adjective better:
  - Better stay here now.
