问题 Which of the following is NOT one of the advantages of mini-computers?
A modern aircraft ______.

选项 A、is run by electronic computers
B、carries a bigger load of electronic apparatus than pay-load
C、does not need mini-computers at all
D、can carry a bigger pay-load if the electronic apparatus carried by it becomes lighter

答案D

解析 根据第一段第4句If it is possible to make any of these smaller,and therefore lighter,the aircraft can carry a bigger pay-load.可知只有答案选项符合文意。pay-load意为"运输工具的净载重量"。
