标题: 求助！！！885-sec-2-1

A fire in an enclosed space burns with the aid of reflected radiation that preheats the fuel, making ignition much easier and flames spreading more quickly.

(A) flames spreading

(B) flame spreads

(D) causing flames to spread（D）

(E) causing spreading of the flames

A为何错啊？与 ignition 并列

如果选A的话，与ignition并列则是做make的宾语make flames do sth. 不会是flames doing，应该是E吧
