Question

Directions: In the question below is given a statement followed by two conclusions numbered I and II. You have to assume everything in the statement to be true, then consider the two conclusions together and decide which of them logically follow beyond a reasonable doubt from the information given in the statement. 

Statement: Plants perform photosynthesis during daylight.

Conclusions:
I: Plants have cells in it
II: Plants have various species.

• A. Only conclusion I follows.
• B. Only conclusion II follows.
• C. Both the conclusions follow.
• D. Neither conclusion I nor conclusion II follows.

Answer 1

Answer:

D. Neither conclusion I nor conclusion II follows.

Solution: To perform photosynthesis, plants need carbon dioxide, water and sunlight. However, every plant has cells regardless of whether or not they perform photosynthesis. Therefore, the argument in statement I cannot be a conclusion of the given statement. Thus, conclusion I does not follow. We cannot determine information about the species of plants from the given statement. Therefore, conclusion II does not follow. Hence, neither conclusion I nor conclusion II follows.
