The sentence that has the correct subject-verb agreement is the second one:
Loud claps of thunder shake the house.
Since the subject <em>loud claps of thunder </em>is in the plural form, the verb <em>shake </em>also has to be in the plural form.
The suffix "-fy" means cause or become. A verbal suffix meaning "to make" "cause to be" "render", "to become", "be made".The suffix was introduced into English in loan words from Old French, but also used the information of new words, usually on a Latin root.
