21A society in which there are many crimes, such as thefts and murders, should not be called “lawless.” That is an abuse of the meaning of words. As a suffix, “-less” means “without,” so “lawless” means “without laws.” However, a society that has no laws has no crimes, because no laws can be broken. A lawless society would, therefore, be a crimeless society. So what some have termed a lawless society should actually be called “crimeful.”

If the statements in the passage are true, which one of the following must also be true?
(A) A society that has laws has crimes.
(B) A society that has no crimes has no laws.
(C) A society that has many laws has many crimes.
(D) A society that has some crimes has some laws.
(E) A society that has many crimes has many laws.

This is called contrapositive

if A -> B

then from this you can only derive that

if not B -> then not A

given that

no laws -> no crimes

contrapositive will be:

if there are crimes there are laws hence D
