EFL teacher and BrE speaker here. Yes we are learning Romanian, but some Romanians are using this course to learn English, so I hardly consider discussing the difference between natural and unnatural English (something this course has rather a lot of) to be a ridculous detail. But then I'm just a language freak. It's all grist to my mill.
What's more, it was given as a possible answer here, so I think it's totally relevant to comment that it's not something a native speaker would normally say, and for this reason wouldn't in fact be accepted in an English test.
And I can confirm what BenYoung says.
1) The use of "much" and "many" in affirmative sentences is extremely formal
2) The adverb "much" is only used after certain verbs, to talk about degree, not quantity, and even then only with a second modifying adverb:
"She loves him very much"
"She loves him a lot"
But we don't say:
X "She loves him much"
The use of "much" here would sound plain weird.
