8. Residents of an apartment complex are considering two possible plans for collecting recyclable trash.
Plan 1 - Residents will deposit recyclable trash in municipal dumpsters located in the parking lot. The trash will be collected on the first and the fifteenth days of each month.
Plan 2 - Residents will be given individual containers for recyclable trash. The containers will be placed at the curb twice a week for trash collection.
Which of the following points raised at a meeting of the residents, if valid, would most favor one of the recycling plans over the other?
(A) Residents will be required to exercise care in separating recyclable trash from nonrecyclable trash.
(B) For trash recycling to be successful, residents must separate recyclable bottles and cans from recyclable paper products.
(C) Penalties will be levied against residents who fail to sort their trash correctly.
(D) Individual recycling containers will need to be made of a strong and durable material.
(E) Recyclable trash that is allowed to accumulate for two weeks will attract rodents.
plan 1的收集时间不也是两周吗，还多几天呢。我觉得plan1与plan2的区别是收集地点不同，另外plan2 还需要 individual containers, 而不是时间，所以我选D. 但大全的答案是E。 不解，请指教～ |
