Which of the following is arranged in decreasing order of extension (from the widest to the narrowest)?
AMathematics, Arithmetic, Numbers/Digits, Prime Numbers ✓ Correct
BPrime Numbers, Numbers/Digits, Arithmetic, Mathematics
CArithmetic, Mathematics, Numbers/Digits, Prime Numbers
DNumbers/Digits, Prime Numbers, Arithmetic, Mathematics
Correct answer: (A) Mathematics, Arithmetic, Numbers/Digits, Prime Numbers — The decreasing extension order is mathematics, arithmetic, numbers/digits, prime numbers, so that is the answer.
Explanation
★The decreasing extension order is mathematics, arithmetic, numbers/digits, prime numbers, so that is the answer.
★Extension is the number of members a term includes.
★Mathematics is the widest field, covering the most.
★Arithmetic is a narrower branch within mathematics.
★Numbers and digits are narrower still, and prime numbers are the narrowest class.
★So from widest to narrowest the order is mathematics, arithmetic, numbers/digits, prime numbers.
