In the following question, the 1st and the last part of the sentence/passage are numbered 1 and 6. The rest of the sentence/ passage is split into four parts and named P, Q, R and S. These four parts are not given in their proper order. Read the sentence/passage and find out which of the four combinations is correct. 1. Over millions of years, the Colorado River wore away rocks as it passed through the area. P. Each layer of rock has a different depth and color. Q. The canyon is made of layers of rock. R. Slowly, the river made the path deeper and deeper.  S. Now, the canyon is surrounded by steep walls on either sides. 6. Geologists have identified almost 40 different layers of rock exposed by the river’s erosion.?

Option 1 : RSQP

The correct answer is option 1 i.e. RSQP.

•  While arranging the parts of the passage, we have to find some grammatical or contextual connections between them-
  • R follows sentence 1 as it refers to the path through which the Colorado river passed.
  • Next is S as it tells the present structure of the canyon.
  • After that is Q as it tells what the canyon is made of.
  • Last is P as it describes each layer of the rock.​

Correct order- Over millions of years, the Colorado River wore away rocks as it passed through the area. Slowly, the river made the path deeper and deeper. Now, the canyon is surrounded by steep walls on either side. The canyon is made of layers of rock. Each layer of rock has a different depth and color. Geologists have identified almost 40 different layers of rock exposed by the river’s erosion.
