The correct answer is:
A. Many students have jobs, and an extended school day would decrease the hours they could work.
A counterclaim is a claim made to offset another claim, especially one made by the defendant in a legal action. In this especific statement, the only counterclaim that responds directly to this claim is the fact that students won't have enough paid hours and that will affect directly their lifestyle and wealthness, involving also their school performance.
B. Teachers already work long hours, and this prevents them from
being able to spend enough time with their families. This counterclaim directly responds to the claim. Instruction time makes reference to teaching time ,so the focus is on teachers' labour .
These statements do not counterargue with the claim:
A. Many students have jobs, and an extended school day would
decrease the hours they could work. The claim sets the focus on teachers not on students' activities after school.
C. Students often come to school hungry, and school lunches don't
provide enough nutrition. The claim does not refere to students' nutrition.
D. Schools often focus on standardized testing as a measurement of
student learning. There is not any information about evaluation.
