Assertion Reason Questions on The Ever-Evolving World of Science
Assertion Reason Questions
Q1. Assertion (A): Scientific exploration often leads to more questions rather than just final answers.
Reason (R): In science, every discovery is considered the end of learning.
(a) Both A and R are true, and R is the correct explanation of A.
(b) Both A and R are true, but R is not the correct explanation of A.
(c) A is true, but R is false.
(d) A is false, and R is also false.
Answer: (c) A is true, but R is false.
Explanation: Scientific exploration encourages continuous questioning and deeper inquiry; it never signifies the end of learning.
Difficulty Level: Moderate
Q2. Assertion (A): Early observations of bird wings and paper planes contributed to the development of real aircrafts.
Reason (R): Curiosity and simple experiments have historically driven major technological innovations.
(a) Both A and R are true, and R is the correct explanation of A.
(b) Both A and R are true, but R is not the correct explanation of A.
(c) A is true, but R is false.
(d) A is false, and R is also false.
Answer: (a) Both A and R are true, and R is the correct explanation of A.
Explanation: Early inspirations from natural observations (like bird wings) and simple experiments (like paper planes) led to advances in real aviation.
Difficulty Level: Moderate
Q3. Assertion (A): The interconnectedness of different fields of science allows discoveries in one area to inspire questions in another.
Reason (R): Chemistry and biology are completely independent fields with no overlap.
(a) Both A and R are true, and R is the correct explanation of A.
(b) Both A and R are true, but R is not the correct explanation of A.
(c) A is true, but R is false.
(d) A is false, and R is also false.
Answer: (c) A is true, but R is false.
Explanation: Different branches of science are interconnected; for example, chemical processes are vital to biological systems.
Difficulty Level: Tough
Q4. Assertion (A): Understanding scientific processes also helps students become more responsible towards environmental challenges.
Reason (R): Scientific learning makes students focus only on technological innovations, ignoring the environment.
(a) Both A and R are true, and R is the correct explanation of A.
(b) Both A and R are true, but R is not the correct explanation of A.
(c) A is true, but R is false.
(d) A is false, and R is also false.
Answer: (c) A is true, but R is false.
Explanation: Scientific learning develops responsibility towards sustainable practices, not just technological advancement.
Difficulty Level: Moderate
Q5. Assertion (A): Observations like the movement of shadows helped early humans develop timekeeping devices.
Reason (R): Early humans understood that light and shadow patterns could predict the weather conditions.
(a) Both A and R are true, and R is the correct explanation of A.
(b) Both A and R are true, but R is not the correct explanation of A.
(c) A is true, but R is false.
(d) A is false, and R is also false.
Answer: (c) A is true, but R is false.
Explanation: Movement of shadows was mainly used for measuring time, not for weather prediction.
Difficulty Level: Moderate/Tough
