II. Bees are essential for biodiversity and food production.

1. A. III-II-I-IV
2. B. IV-I-II-III
3. C. II-I-III-IV (Correct answer)
4. D. I-III-IV-II

Correct Answer

Option C — II-I-III-IV

Detailed Solution & Explanation

The correct answer is II-I-III-IV.

Key Points

• II (Bees are essential) -> I (They pollinate plants) -> III (population declining) -> IV (reasons: habitat loss and pesticides).

Additional Information

• Find the opening sentence first: it introduces the subject by name and needs no prior context. Only II does that — *Bees are essential…* — while I, III and IV all begin with words that point backwards.
• Then follow the pronoun and connector chain: I opens with *They*, which must refer to the bees just named; III opens with *However*, signalling the contrast that follows the positive description; IV opens with *this*, referring to the decline in III.
• That yields II → I → III → IV, moving from importance, to the reason for it, to the problem, to its cause — a standard expository order.
• In parajumbles, the reliable anchors are pronouns without antecedents, connectors (however, therefore, moreover) and demonstratives (this, such, these); each one must have something earlier to attach to.
