Galen wrote the statement "If the sum of the digits in a number is divisible by 3, the original number is divisible by 3." Which statements are true regarding his work? Choose three correct answers.

The statement has the conditional form “If P, then Q”: P is “the sum of the digits in a number is divisible by 3,” and Q is “the original number is divisible by 3.” Adding “then” makes the wording in choice B equivalent, and choice C correctly identifies the hypothesis P. The claim can be checked mathematically, so it can be proven true or false, as choice E says. The conclusion does not come first, and a conditional can be understood even when “then” is omitted.
