hard · LSAT Logical Reasoning

Which one of the following arguments exhibits a pattern of flawed reasoning most similar to that in the critic's argument?

1. All members of the touring choir can read music, and every alto in the ensemble is a member of the touring choir; so any alto who cannot read music is not in the ensemble.
2. Every grant the foundation approved last year went to a registered charity, and the foundation stopped funding overseas projects before last year; so any approved grant to an overseas project went to a registered charity.
3. All of the firm's audited clients filed on time, and the firm audited only clients with revenue above a threshold; so any client below that threshold who filed late was not audited by the firm.
4. Each book reviewed in the journal was published by an academic press, and the journal reviews only nonfiction; so any work of fiction from an academic press was not reviewed in the journal.
5. All of the recovered manuscripts predate the fire, and the abbey's scriptorium closed before the fire; so any manuscript produced in that scriptorium that was recovered predates the fire.
