The sentences given below, when properly sequenced, form a coherent paragraph. Each sentence is labelled with a number. Decide on the most logical order and enter the sequence of numbers in the space provided.

  1. In drought conditions, water often depletes in the topsoil and remains accessible only in the deeper subsoil layers.
  2. A new study gives new insights into how the acid changes root growth angles to enable plants to reach out deeper subsoils in search of water.
  3. Plants rely on their root systems, the primary organs for interacting with soil, to actively seek water.
  4. Abscisic acid plays an important role in helping plants adapt to these challenging conditions.

Entered answer:

Solution

✅ Correct Answer: 3142

The passage talks about how plants adapt their root systems during drought conditions.

Link A (3 → 1): Sentence 3 introduces plants seeking water, then sentence 1 specifies the drought challenge they face.

Link B (1 → 4): Sentence 1 mentions "drought conditions" and sentence 4 uses specific reference "these challenging conditions" referring back.

Link C (4 → 2): Sentence 4 mentions "Abscisic acid" and sentence 2 uses specific reference "the acid" referring to it.


Introduction: Sentence 3 is the introducing sentence because it establishes the general concept of plants using roots to seek water.

Conclusion: Sentence 2 is the concluding sentence because it presents specific research findings about the adaptation mechanism.


Assembling: The sequence flows from general plant behavior to drought challenges to acid adaptation to research findings.

Hence the correct order is 3142
