Assertion–Reason (Evaluate Truth and Explanation): Assertion (A): Bread that develops mould on it has to be thrown away. Reason (R): All moulds are poisonous.
-
ABoth (A) and (R) are true, and (R) is the correct explanation of (A).
-
BBoth (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, but (R) is true.
-
EBoth (A) and (R) are false.
Answer
Correct Answer: (A) is true, but (R) is false.
Explanation
Introduction / Context:Food safety questions often hinge on conservative practice versus over-generalized reasons. We must assess both statements independently and the explanatory link.
Given Data / Assumptions:
- (A) Advises discarding mouldy bread.
- (R) Claims all moulds are poisonous.
Concept / Approach:Even if not every mould produces dangerous mycotoxins, porous foods like bread allow hyphae/mycelium to spread beyond visible patches, making discarding prudent.
Step-by-Step Solution:
1) (A) is sound: for soft/porous foods, safe practice is to discard when mould is present.2) (R) is false because “all moulds are poisonous” is an overstatement; toxicity varies by species/conditions.3) Therefore, (R) cannot be the correct explanation of (A).Verification / Alternative check:The reason to discard is risk of invisible spread and potential toxins, not that all moulds are poisonous.
Why Other Options Are Wrong:(a) and (b) require (R) true; (d) flips truth values; (e) denies established food-safety advice.
Common Pitfalls:Accepting universal claims without exceptions; assuming visible mould equals the entire contaminated region.
Final Answer:Option C: (A) true, (R) false.
