    we received calls from people down the road two years ago

    D

    正确答案： B
    解析：
    词句理解题。理解本句的关键是看Marilyn是在什么样的情况下说这句话的，即要看此句的前一句——申请者过多，而拒收率也更高。因此，直接引语肯定是补充说明或进一步阐述这种情况的。另外，本句中的two years down the road指的是从现在开始的两年后，含有“提前”之意。而本文的主旨是入学问题，故spots是指能入学的名额。故D项为正确答案吧。A项中的parking space意为“停车位”。B项中的use of the place意为“使用这个地方”，都曲解了引语中spots的意思。而B、C两项中的two years ago则曲解了这一句中的two years down the road一处。
