補(bǔ)全短文：

A.Life seems to have grown too tough for black robins.
B.Is it any business of ours whether the black robin survives or dies out?
C.The organizers say that Little Mangere should then be restocked（重新準(zhǔn)備)with the robin's food.
D.Energetic steps are being taken to preserve the black robin.
正確答案：B
答案解析：前后句分別為問(wèn)句，選項(xiàng)B與其共同構(gòu)成了三個(gè)排比的問(wèn)句結(jié)構(gòu)。所以，選項(xiàng)B是合適的選項(xiàng)。
