Answer: In the research context, the term validity most commonly refers to whether a project is <em>based ion truth or reason and indicates how sound a</em> <em>research is.</em> <em>Validity claims are solid claims that represent the truth.</em> Also, it refers to how well an instrument measures what it intended to measure.

The correct answer is D) After the big game, my family wanted to celebrate. To understand why it's important to know that an adverbial phrase is when the adverb is used to describe <u>when, where, how, how often or how long</u> something happens. In this case, we have an adverbial phrase of time because it states when something happens: "<em>After the big game</em>" this part help us to understand when the action happens , also the reason behind why they wanted to celebrate and at the end, it adds more detail to the sentence "<em>My family wanted to celebrate</em>".
The adverb is placed at the beginning of the sentence so we can cross out the <u>option B</u> and also the <u>option C.</u> The option B is describing where the family come from and "from out of town" doesn't function here as an adverb, the function here is to describe the precedence of the family but no more details. <u>The option A</u> is incorrect because when we use "<em>entire</em>" as an adverb it only goes after a verb and in this case, we have "<em>entire family</em>" so it goes with a noun and it's not correct as an adverbial phrase.
D) The discovery that the Universe is expanding was the greatest discovery of the century.
