Statements:
1. No monkey is a chimpanzee.
2. Some chimpanzees are gorillas.
Conclusions:
I. Some gorillas are not monkeys.
II. Some monkeys are not gorillas.
Which conclusion(s) logically follow?
A. Only conclusion II follows
B. Neither I nor II follows
C. Only conclusion I follows
D. Both I and II follow
Answer: Option C
Solution (By JKExamLibrary)
Since some gorillas are chimpanzees, and no chimpanzee is a monkey, those specific gorillas can never be monkeys. Thus, some gorillas are not monkeys (I follows). We don't know the relationship between the rest of the gorillas and monkeys, so II doesn't follow.
Statements:
1. All clouds are rain.
2. All rain is water.

II. All clouds are water.
Which conclusion(s) logically follow?
Statement:
Consuming too much sugar leads to obesity and diabetes.
Conclusions:
I. Sugar should be completely banned.
II. People who consume less sugar are completely safe from diabetes.
Which conclusion(s) logically follow?
Explanation:
The statement highlights the danger of 'too much' sugar, not sugar in general, making a total ban (I) an illogical extreme. Also, diabetes could be caused by genetics or other factors, so consuming less sugar does not guarantee 'complete safety' (II). Neither follows.
