【答案解析】解析：联接词题。考查句内逻辑关系。空格所缺词应该是联接词。它所联接的前半部分意为“制作一枚一美分的硬币，需要1．6美分”，后半部分意为“这种硬币比其他面额的硬币生产得多”。根据常理，既然制作成本比实际面值还高，应该少铸造这种硬币才是，但事实却是more pennies are produced。由此可判断，此处需要填入表示让步关系的联接词。B项符合题意。
单选题
【B16】
【正确答案】
C
【答案解析】解析：语义逻辑题。这句话的关键是had no such luck“没有如此的好运”，“好运”指的就是前一句话中提到的：即使造一美分硬币需要1．6美分，这种硬币还是比其他面额的硬币生产得多。而下文由表并列关系的连词and引导分句．指出“10万美元的纸币虽然印刷过却从未发行过”，综合分析前后的逻辑关系，可以判断出这里说的500元面值等纸币应该是“短命的”，因此，C项符合题意。
