- B.The library also extended its weekend opening hours during that month.
- C.The membership fee had already been reduced once in the previous year.
- D.Some members renewed their memberships earlier than usual that month.
Kunci jawaban & pembahasan
Jawaban: The library also extended its weekend opening hours during that month.
The conclusion claims the discount was the sole cause, but the simultaneous extension of opening hours provides an alternative explanation for the rise in memberships, weakening the causal claim.
