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:
(a) All curtains are sheets.
(b) Some sheets are shawls.

Statements:
(a) All curtains are sheets.
(b) Some sheets are shawls.
(c) Some covers are sheets.

The venn diagram of the information from above statements looks as 

Conclusions I. Some curtains are covers.

From the diagram the statement some curtains are covers is not true.

Conclusions II. Some shawls are covers.

We can see in the diagram, that there is no intersection in the shawls and covers. So, conclusion II is also false.
