Question 1

Statement: A pharmaceutical company tested a new pain reliever on 2,000 volunteers. Participants who took the drug reported 45% less pain on average than those who took the placebo.

Inference: The new pain reliever is more effective than the placebo at reducing pain.

Accepted Answer

True

Answer

The controlled study directly shows that the drug reduced pain by 45% more than placebo, making this inference definitively true from the data.

Question 2

Statement: Since the new CEO took over two years ago, the company's annual revenue has grown by 35%. Employees report higher morale.

Inference: The new CEO is responsible for the revenue growth.

Accepted Answer

Insufficient Data

Answer

Leadership change coincides with revenue growth and morale improvement, but external market conditions or prior strategic decisions could also explain the results.

Question 3

Statement: Historical records show that no volcanic eruption has occurred in this region for over 500 years.

Inference: A volcanic eruption will not occur in this region in the next 10 years.

Accepted Answer

Insufficient Data

Answer

Past inactivity reduces perceived short-term risk but does not provide sufficient data to rule out a future eruption within any specific time frame.

Question 4

Statement: Students who read for at least 30 minutes every day scored an average of 20 percentile points higher on reading comprehension tests than students who did not.

Inference: Daily reading practice improves reading comprehension.

Accepted Answer

Probably True

Answer

The strong correlation is consistent with the inference, and it is supported by established educational research, though the study's design is not described as experimental.

Question 5

Statement: The city banned plastic bags at all retail stores. Within one year, plastic bag litter in the city's parks decreased by 72%.

Inference: The plastic bag ban was the main reason for the reduction in park litter.
