• A. CDE
• B. CEF
• C. ACD
• D. BEF

Hint:

For grouping, look for statements that share terms and can be linked either directly or through a universal-particular deduction.

Answer 1

The Correct Option is A

C — "All toys are dolls." — This universally includes toys inside the category of dolls.
D — "Some toys are nice." — This is a particular affirmative statement, which can be derived if toys are part of dolls and dolls are nice.
E — "Some nice things are dolls." — This is also a particular affirmative statement that can logically follow from the universal statements involving dolls and niceness.
Thus, C, D, and E are logically connected because they share terms (toys, dolls, nice things) in a consistent manner and allow mutual inference.
