In the following question, the first and the last parts of the sentence/passage are numbered 1 and 6. The rest of the sentence/passage is split into four parts — P, Q, R, and S. These four parts are not given in their proper order. Read the sentence/passage and find the most logical order of the parts between 1 and 6.
1. The Earth's climate has changed over centuries.
P: But current warming is caused by human actions.
Q: Historically, it changed due to natural causes.
R: Burning fossil fuels increases greenhouse gases.
S: Deforestation worsens the problem.
6. This calls for urgent action.
Show answer & explanation
Correct answer: B
Explanation
The most logical order for the passage is QPSR.
1. (Fixed): The Earth’s climate has changed over centuries.
Q: Historically, it changed due to natural causes. (This directly follows sentence 1 by elaborating on how climate changed in the past.)
P: But current warming is caused by human actions. (The word "But" creates a contrast between historical natural causes and current human-driven causes.)
S: Deforestation worsens the problem. (This introduces a specific human action that contributes to the warming mentioned in P.)
R: Burning fossil fuels increases greenhouse gases. (This provides another major cause, leading logically to the conclusion.)
6. (Fixed): This calls for urgent action.
