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?

A Children from higher-income families tend to have more books at home and also receive more parental reading time.

B The study controlled for factors such as parental education level, household income, and the child's baseline cognitive ability at the start of the study.

C Some children who were read to for 20 minutes per day still scored below the average of children read to for less than 5 minutes.

D Standardized vocabulary tests are widely regarded as an unreliable measure of true language ability.

The city plans to replace all streetlights with energy-efficient LED bulbs, claiming that the switch will reduce electricity costs by 50 percent. The city treasurer calculates that the savings will cover the cost of installation within three years. Environmental groups support the plan, but some residents worry about the impact of blue-rich LED light on sleep patterns and stargazing. Which of the following, if true, most supports the treasurer's calculation that savings will cover installation costs within three years?

A The total cost of purchasing and installing LED bulbs for all streetlights is estimated at 12 million dollars, and the annual electricity savings are projected to be 4 million dollars.

B Other cities that have switched to LED streetlights have reported varying degrees of electricity cost savings, ranging from 30 to 60 percent.

C LED bulbs have a longer lifespan than traditional streetlights, reducing the frequency of replacements.

D Environmental groups have pledged to help fund the LED conversion program through grants and donations.

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 A similar congestion pricing program in London reduced traffic by 30% in its first year and generated revenue that was successfully reinvested in public transit.

B Some residents who work downtown have complained that the fee represents a regressive tax that disproportionately affects lower-income workers.

C Public transit ridership in the city has increased by 10% since the congestion pricing program began, suggesting that some drivers have switched to transit.

D The fee level in the city is currently lower than the fee charged in Stockholm, which implemented a similar program in 2006.

A new study suggests that consuming dark chocolate daily can improve cardiovascular health. Researchers followed 500 participants for five years and found that those who consumed at least 20 grams of dark chocolate per day had a 30% lower risk of heart disease. Which of the following, if true, would most strengthen the conclusion?

A Some participants who did not consume dark chocolate also ate other types of chocolate.

B Participants who consumed dark chocolate also reported higher levels of physical activity and better overall diets.

C The study was funded by a dark chocolate manufacturing company.

D Dark chocolate contains flavonoids, which have been shown in laboratory studies to reduce inflammation and improve blood vessel function.

A study of 10,000 readers found that those who read fiction for at least thirty minutes per day scored higher on tests of emotional intelligence than those who read nonfiction or used social media for equivalent amounts of time. The researchers concluded that reading fiction causally improves emotional intelligence, perhaps because it requires readers to simulate the perspectives and emotions of complex characters. Which of the following, if true, most strengthens the researchers' conclusion?

A A follow-up study found that participants who were randomly assigned to read fiction for three months showed a statistically significant increase in emotional intelligence scores compared to a control group.

B People with high emotional intelligence tend to prefer reading fiction over other genres.

C The fiction readers in the original study also tended to engage in more face-to-face social interactions than the other groups.

D The emotional intelligence test used in the study was developed by researchers who specialize in literary analysis.

A new study found that children who grow up in households with access to a wide variety of books score higher on vocabulary tests than children without such access. Based on this finding, a education policy advisor recommends that all families receive free books to improve children's language development. Which of the following, if true, most helps justify the advisor's recommendation?

A Providing free books to families has been shown in previous programs to increase the number of books available in the home.

B Vocabulary test scores are the most important measure of a child's overall academic readiness.

C Children who attend preschool tend to have better vocabulary scores regardless of home environment.

A In cities with similar zoning restrictions, housing prices have increased by an average of 15 percent over the past five years.

B Some residents in the neighborhoods support the zoning law because they value quiet streets and green spaces.

C High-rise buildings typically provide more housing units per acre than low-rise buildings.

D The city council president has a background in urban planning rather than real estate development.

A Competing drugs in the same therapeutic category have been associated with severe side effects in a significant minority of patients.
