Question

Under the same fact-situation as in Q.158, which statement, if true, {seriously weakens the argument?}

• A. Matter is not bound by space.
• B. Matter is indestructible.
• C. Whatever exists is not necessarily affected by motion.
• D. What is not matter is also vulnerable to motion.

Hint:

To weaken, target the argument’s {hinge}—the premise without which the conclusion cannot be reached.

Answer 1

The Correct Option is D

The argument presented in the problem suggests that matter is susceptible to motion, potentially implying that non-matter is not. To weaken this argument, one must show that non-matter is also affected by motion. This would negate the implied distinction between matter and non-matter regarding their interaction with motion.

Let's analyze the options:

• Matter is not bound by space: This statement does not address the effect of motion on matter or non-matter, thus it does not weaken the argument.
• Matter is indestructible: While this suggests matter can't be destroyed, it doesn't directly relate to how matter or non-matter is affected by motion.
• Whatever exists is not necessarily affected by motion: This statement provides a general observation but does not specifically address the effect of motion on non-matter.
• What is not matter is also vulnerable to motion: This statement directly challenges the assumption that only matter is affected by motion. By indicating that non-matter is also vulnerable, it weakens the distinction made in the argument, thus seriously undermining it.

Therefore, the statement that What is not matter is also vulnerable to motion seriously weakens the argument by showing that motion affects both matter and non-matter alike, thus negating any implied lack of effect on non-matter.
