A study found that countries with higher levels of income inequality tend to have lower levels of social mobility. Based on this correlation, a policy institute recommends that governments implement progressive taxation and expand social programs to improve economic mobility. Which of the following, if true, would most strengthen the recommendation?

A city implemented a congestion pricing scheme requiring drivers to pay a fee to enter the downtown core during peak hours. Within three months, traffic volume in the zone decreased by 18%, and air quality improved measurably. The city transportation department plans to expand the program to additional zones and increase the fee over time, arguing that the higher costs will further reduce traffic and generate revenue for public transit improvements. Which of the following, if true, most strongly supports the transportation department's plan?

A recent study found that employees who participated in a four-day workweek reported 23 percent higher job satisfaction than those on a five-day schedule, even though overall productivity remained unchanged. Which of the following, if true, would most strengthen the conclusion that the four-day workweek causes higher job satisfaction?

A pharmaceutical company developed a drug that reduces the symptoms of a chronic autoimmune disease in 80% of patients. The drug, however, causes serious side effects in 15% of users, including liver damage requiring monitoring. Despite these side effects, the company argues that the drug should be widely prescribed because the alternative treatments benefit only 40% of patients and have milder side effects. Which of the following, if true, would most strengthen the company's argument?

The new education policy requires all high school students to complete a semester-long course in financial literacy before graduating. The superintendent argues that this will prepare students for the financial decisions they will face as adults, such as managing bank accounts, understanding credit cards, and planning for retirement. Critics counter that adding this requirement will overcrowd the curriculum and force students to drop other important subjects. Which of the following, if true, most supports the superintendent's argument?

A team of researchers studied the reading habits of 500 children aged 5 to 10. They found that children who were read to by a parent at least 20 minutes per day scored, on average, 15 percent higher on standardized vocabulary tests than children who were read to for less than 5 minutes per day. The researchers concluded that regular parental reading during early childhood causally improves later vocabulary development. Which of the following, if true, most strengthens the researchers' conclusion?

The new policy was intended to reduce traffic congestion by encouraging commuters to use public transportation. However, six months after implementation, surveys showed that the majority of commuters still preferred driving their own cars. The policy maker therefore claimed that the policy had failed to change commuter habits. Which of the following, if true, would most strengthen the policy maker's argument?

The city council approved a new zoning law that restricts high-rise construction in residential neighborhoods. The council president stated that the law was necessary to preserve the character of these neighborhoods and prevent overcrowding of local infrastructure.
