Question

read the passage. then, select the antonym of the word in bold. every year, americans spend billions of dollars on supplements that promise to improve their health and fitness levels. all too often, though, the manufacturers of these products make spurious claims about their effectiveness. the federal trade commission, in partnership with other government agencies, combats deceptive advertising by examining these products to ensure that the claims are valid. select the antonym that helps you understand the meaning of the word obsolete. as technology continues to evolve, items that are valuable today may be thrown in the trash tomorrow. typewriters, public pay phones, and cassette tapes are all examples of technologies that were once current but - thanks to computers, cell phones, and digital audio - are now obsolete.

The word "spurious" means false or not genuine. Its antonym should mean true or genuine. In the context, "valid" is an antonym as the Federal Trade Commission checks for valid (true) claims as opposed to spurious (false) ones.

Answer:

valid
