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?
Explanation:
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 water is liquid.
2. Some ice is water.
Conclusions:
I. Some ice is liquid.
II. All ice is liquid.
Which conclusion(s) logically follow?
Explanation:
The part of ice that is water must also be liquid because all water is liquid. Therefore, some ice is liquid (Conclusion I). We do not know about all ice, so Conclusion II does not necessarily follow.
