A logical reasoning question

E. If Xiao Sun did not go on the trip, then Xiao Zhao and Xiao Li would not both go.

In fact, the original question says that if Xiao Zhao goes, then Xiao Qian, Xiao Sun, and Xiao Li will all go.

But conversely, the other three will not go to Xiao Qian. It doesn't matter to Zhao. Whether they go or how many they go has nothing to do with Xiao Zhao.

First of all, A. If Xiao Zhao did not go traveling, then at least one of Xiao Qian, Xiao Sun, and Xiao Li did not go. B． If Xiao Zhao didn't go traveling, then Xiao Qian, Xiao Sun, and Xiao Li didn't go either. C． If Xiao Qian, Xiao Sun, and Xiao Li all go traveling, then Xiao Zhao will also go

Secondly: D. If Xiao Li did not go on the trip, then Xiao Qian and Xiao Sun would not both go. The original question didn't even mention whether there was any relationship between the three of them, so it was denied.

Finally: E. If Xiao Sun didn't go traveling, then Xiao Zhao and Xiao Li wouldn't both go. Xiao Sun didn’t go, then Xiao Zhao didn’t go----------because if Xiao Zhao went, Xiao Sun would go (if Xiao Zhao went to travel, then Xiao Qian, Xiao Sun and Xiao Li would Go together) --- Then it is right that Xiao Zhao and Xiao Li will not both go.
