Rearrange the following sentences to form a coherent paragraph:
1. This process, a cornerstone of evolution, ensures that only individuals best suited to their environment survive to reproduce.
2. The diversity of life on Earth is the result of a gradual process of change over vast spans of time.
3. This leads to the gradual accumulation of favorable traits within a population.
4. It begins with inherited variation among individuals, where some possess characteristics that give them an advantage over others.
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 2, 4, 3, 1.
Logical flow:
-
Sentence 2 introduces the broad idea: life’s diversity results from gradual change.
-
Sentence 4 explains how the process begins: inherited variation.
-
Sentence 3 tells what this variation leads to: accumulation of favorable traits.
-
Sentence 1 concludes by naming the process (natural selection) and explaining its role in evolution.
Correct sequence: 2 → 4 → 3 → 1
Final paragraph
The diversity of life on Earth is the result of a gradual process of change over vast spans of time. It begins with inherited variation among individuals, where some possess characteristics that give them an advantage over others. This leads to the gradual accumulation of favorable traits within a population. This process, a cornerstone of evolution, ensures that only individuals best suited to their environment survive to reproduce.
Hence, the chosen option will be correct.
