Answer:
D. On average, teenagers who live in middle-income neighborhoods have better study skills than those who live in low-income neighborhoods.
Explanation:
The difference in the neighbourhoods will significantly impact if middle-income teenagers have more time to study and also have enough time to recreate.
Having fewer things to worry will generally help them in their learning and developing process.
To the contrary, children that lack the standards for a healthy learning environment will struggle to learn at the same rate.
For example children in low-income settings, external pressures can lead them to bad study habits, or even the lack of time necessary to review and learning since many will likely help in duties that are normally part of the household.
