ESL/EFL Test #11 "Losing It", answer 6

I'm afraid that kind of humour is totally without effect him so you'll have to explain it more simply.

Correct answer: (a) without effect

Your answer was: incorrect
I'm afraid that kind of humour is totally without sense him so you'll have to explain it more simply.
_________________________

Ignoring the superfluous 'him' in the sentence, I had thought both a) and c) were possible depending on the 'thinking thread' of the speaker before I chose c). Since c) is incorrect, can I see it's because 'be lost on sb.' should be strictly under the meaning of ineffective?

Hi Haihao

The expression 'be lost on' means 'have no effect or influence on'. This is often due to a lack of comprehension. In the test sentence the man didn't react to the humor problably because he didn't understand it. And if you don't understand a joke, it will not have the intended effect on you.

Hi,

You can also use the verb 'lose' in an active sense when you want to explain to someone that you don't follow an argument as in: I'm sorry, you'll have to explain that again - you've lost me.

One more example with the expression "be lost on", Haihao .
Ex. Martin gave Joe a gentle hint but it was lost on (upon) him.

In the answer it was written" .... totally without effect him, why can't we say without effect on him or just leave out him and say totally without effect? Please explain!
