Consider archeology - even though one can not perform repeatable experiments , hypotheses may still be supported . For instance , an archeologist can hypothesize that an ancient culture existed based on finding a piece of pottery . Further hypotheses could be made about various characteristics of this culture , and these hypotheses may be found to be correct or false through continued support or contradictions from other findings . A hypothesis may become a verified theory . A theory is a tested and confirmed explanation for observations or phenomena .
Please check all the words that can be used instead of the target word in the same context. Note that the morphology of the target (third person singular, past tense etc.) is considered to be applied to the candidate automatically in the process of paraphrasing.
