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 follows from the statements.
Statements:
I. All X are A.
II. Some R are X.
Conclusions:
I. Some A are R.
II. All R are A.
Show answer & explanation

The least possible Venn Diagram for the given statements is drawn below:
Conclusions:
I. Some A are R → True (As all X are A, and some R are X, so some A are R is also true.)
II. All R are A → False (It is possible but no definite conclusion can be drawn.)
