      A 1-B, 2-D Correct Answer Incorrect Answer
      B 1-C, 3-B Correct Answer Incorrect Answer
      C 1-C, 2-D Correct Answer Incorrect Answer
      D 1-C only Correct Answer Incorrect Answer
      E 1-C, 2-D, 3-A Correct Answer Incorrect Answer

      Solution

      Sentence 1 → Error in Part C Subject: → “Recent advances” (plural) Verb used: → “has enabled” Correct: → have enabled Rule: When the actual subject is plural, expressions like “together with…” do not change subject number. Sentence 2 → Error in Part D The sentence uses: → “few analysts have anticipated” But after: → “No sooner had…” the reference remains in completed past context. Correct: → few analysts had anticipated Sentence 3 → Correct. Hence, option (3).
