Directions: In this section each item consists of six sentences that comprise a passage. The first and sixth sentences are given in the beginning as S1 and S6. The sequence of the middle four sentences has been jumbled up and labelled as P, Q, R and S. You are required to find the proper sequence of the four sentences and mark your response accordingly on the Answer Sheet.

S1: All the different parts of our eye help us to see.

S6: These electrical signals then travel through the optic nerve to the brain which in turn converts these signals into the images we see.

P: The iris, which is the coloured part of the eye, controls how much light the pupil lets in.

Q: Next, light passes through the lens, the clear inner part of the eye, which focuses this light on the retina.

R: First, light passes through the cornea, the clear front layer of the eye, and enters the eye through an opening called the pupil.

S: When it hits the retina, special cells called photoreceptors convert the light into electrical signals.

This question was previously asked in
CDS 2 2026 Maths Question Paper (13-Sep-2026)
The correct answer is

R P Q S

S1 states that all parts of the eye help us see. R explains that light first passes through the cornea and enters via the pupil, P explains the iris's role in controlling how much light passes through, Q explains that light then passes through the lens onto the retina, and S explains that photoreceptors convert this light into electrical signals, leading to S6's conclusion about signals reaching the brain. The correct sequence is R-P-Q-S.
