Question

If a researcher wanted to search for journal articles on Term A, but wanted to exclude articles with Term B, which logical operator should the researcher use? A) AND B) OR C) NOT D) XOR

Answer 1

C) NOT

Step-by-step explanation:

"and" looks for both a, and b
"or" looks for one or the other
"xor" looks to see if the two data values are the same, and if they are, the output is 0, but if they're different, the output is 1
