  1. But the attention of the layman, not surprisingly, has been captured by the atom bomb, although there is at least a chance that it may never be used again.
  2. Of all the changes introduced by man into the household of nature, [controlled] large-scale nuclear fission is undoubtedly the most dangerous and most profound.
  3. The danger to humanity created by the so-called peaceful uses of atomic energy may, however, be much greater.
  4. The resultant ionizing radiation has become the most serious agent of pollution of the environment and the greatest threat to man's survival on earth.

Solution

✅ Correct Answer: 2413

Step-by-step process:

First, look for the opening sentence -> Sentence 2 starts broadly with "Of all the changes..." which introduces the main topic of nuclear fission dangers.

Thenwe need the natural follow-up -> Sentence 4 explains why nuclear fission is dangerous (ionizing radiation), building directly on sentence 2.

Next, we look for contrast words -> Sentence 1 starts with "But" showing a shift to what people focus on (atom bombs vs. general nuclear dangers).

Finally, the concluding thought -> Sentence 3 uses "however" to add the final point about peaceful atomic energy being potentially more dangerous.

From passage: "Of all the changes introduced by man into the household of nature, [controlled] large-scale nuclear fission is undoubtedly the most dangerous and most profound."

Thought process: Broad introduction -> Specific explanation -> Contrasting public focus -> Final deeper concern

Topic introduction (2) -> Why it's dangerous (4) -> But people focus on bombs (1) -> However, peaceful uses may be worse (3)


The sequence flows as: 2413

  • Sentence 2 sets up the big picture
  • Sentence 4 explains the specific danger
  • Sentence 1 contrasts with public perception
  • Sentence 3 concludes with an even greater concern

This creates a logical progression from general statement -> explanation -> contrast -> final warning.
