Read the given statements and conclusions carefully. Assuming that the information given in the statements is true, even if it appears to be at variance with commonly known facts, decide which of the given conclusions logically follow(s) from the statements.
Statements:
Some planets are stars.
All stars are satellites.
Conclusions:
I. All satellites are stars.
II. Some satellites are planets
Show answer & explanation
Correct answer: D
Explanation
The correct answer is Option 4. i.e. Only conclusion II follows.
The least possible Venn Diagram for the given statements is drawn below:
Conclusions:
I. All satellites are stars → False (It is possible but no definite conclusion can be drawn.)
II. Some satellites are planets → True (As some planets are stars, and all stars are satellites, so, some satellites are planets is also true.)
Hence, Only conclusion II follows.
