Question 1 • 2001310 Earth Science Sem 1 - Pearson
A pharmaceutical company claimed that experiments showed that its drug could effectively reduce the growth of cancer cells by 35 percent. However, when five independent laboratories conducted the same experiment, they measured a reduction rate of only 5–8 percent.How did these laboratories show that the pharmaceutical company’s claims were invalid?
Answer
A
The labs used the pharmaceutical company’s inadequate data.
B
The labs produced false data.
C
The labs recorded data incorrectly.
D
The labs were unable to reproduce the pharmaceutical company’s data.
Explanation
The five independent laboratories repeated the experiment but measured only a 5–8 percent reduction, rather than the claimed 35 percent. Their results therefore failed to reproduce the company’s reported finding, which undermines the claim. The correct choice is D, “The labs were unable to reproduce the pharmaceutical company’s data.”
