Question 1

Researcher Elena Vance hypothesizes that birds in the city of Oakhaven nest more often in non-native ornamental trees than in native oaks because the ornamental trees offer denser foliage cover. Which finding, if true, would most strongly support her hypothesis?

Accepted Answer

In plantings where the two kinds of tree had been pruned to the same foliage density, the birds nested in each about equally often

Answer

Native oaks in Oakhaven host a greater variety of insects than the ornamental trees do

Answer

Across Oakhaven, nests built in ornamental trees fledge more chicks than nests built in oaks

Answer

Most Oakhaven birds that nest in ornamental trees feed in the native woods nearby

Question 2

A study of remote work at the firm TechFlow found that 72 percent of employees working from home reported higher daily output, while 48 percent of employees on a hybrid schedule reported the same. Among employees working exclusively in the office, 55 percent reported higher daily output. Which statement do these results support?

Accepted Answer

A higher percentage of the fully remote employees than of the office-based employees reported higher daily output.

Answer

The hybrid model is the most effective of the three arrangements for raising output at TechFlow.

Answer

Working from home causes a 24 percentage point increase in the output of TechFlow employees.

Answer

The office arrangement produced lower reported output than the hybrid arrangement for most employees.

Question 3

Writer Julian Thorne claims that the fall in local newspaper readership in the town of Greystone is chiefly due to the rise of social media as a source of news. Which finding, if true, would most directly weaken his claim?

Accepted Answer

Surveys of Greystone residents who stopped taking the paper find that most gave the paper's cuts to local investigative reporting as their reason

Answer

Social media use in Greystone rose by forty percent over the same five years

Answer

Younger Greystone residents get most of their news from digital newsletters rather than from social media feeds

Answer

Greystone's newspaper has reduced its print run twice since the decline in readership began

Question 4

In a trial of a new sleep aid, 65 percent of participants in the treatment group reported improved sleep quality, against 30 percent of participants in the placebo group. Separately, 20 percent of the treatment group reported mild headaches. Which conclusion do these results support?

Answer

The sleep aid improves sleep quality for everyone who takes it.

Answer

The sleep aid produces headaches in half of those who take it.

Answer

A higher percentage of the treatment group than of the placebo group reported improved sleep quality.

Answer

The placebo group reported a greater improvement in sleep quality than the treatment group.

Question 5

Biologist Sarah Chen hypothesizes that the migration of the invented silver-winged butterfly is governed by temperature gradients rather than by where food is available. Which finding, if true, would most strongly support her hypothesis?

Answer

The butterflies migrate toward areas of abundant nectar even when temperatures there are unfavorable.

Answer

Migration timing has stayed much the same across years whose temperature profiles differed considerably.

Answer

The butterflies follow prevailing wind currents whose paths are unrelated to temperature.

Answer

The butterflies alter their route when local temperatures shift, even in years when food availability stays constant.
