Two trials are conducted for an experiment. In Trial A, the measured
value is 240, while the actual value is 200. In
Trial B, the measured value is 195, while the
actual value is 240. An assistant says that
Trial B has the greater percent error. Is the
assistant correct? Explain.

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
