Passage Summary: If there's no homework to turn in, students won't do the reading, and if they don't do the reading, they won't get an A.

Conclusion: No student in a class with reading assignments but no written homework will earn a high grade.

Reasoning: Students will not finish their reading assignments if they aren't required to turn in written work related to those readings.

Analysis: There is a logical gap between the premise (students won't do the reading) and the conclusion (students won't get high grades). The argument assumes that you cannot get a high grade without completing the reading assignments. To make this argument airtight, we need a 'Sufficient Assumption' that explicitly connects these two terms. Look for an answer that states something like 'Completing all reading assignments is necessary for receiving a high grade.'
