Mr. roosevelt's speech had an unexpected__on the audience. which word should go in the blank space effectation, affection, affect, effect

Effect

effect

Explanation:

affect = (verb) to influence or impact something

vs

effect = (noun) consequence, outcome, result

vs

effectation = not a real word

vs

affection = (noun) a feeling of fondness or love

The word 'effect' should go in the blank because Mr. Roosevelt's speech had a physical impression on the audience. The blank can't be filled by a verb, so the the answer must be 'effect' or 'affection'. Since 'affection' does not make sense in this context, 'effect' is the best answer.
