Directions: In this section, each item consists of six sentences of a passage. The first and sixth sentences are given in the beginning as S1 and S6. The middle four sentences in each have 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. The architecture of quantum computers signifies a leap forward in computing power.

S6. This opens fascinating possibilities for solving problems that were previously thought insurmountable.

P. Unlike traditional computers, which use bits as the smallest unit of information, quantum computers utilize qubits.

Q. This allows quantum computers to perform complex calculations at unprecedented speeds.

R. The property of superposition and entanglement grants these qubits this superior computational ability.

S. Furthermore, this advancement is poised to revolutionize fields such as cryptography, drug discovery, and climate modeling.
