Because or because of?

I'm not getting any further with sentences 2 and 5.

In the article it is related to the sentence "its growing at an amazing 40-60 per cent a year". Can I just take it over without the "amazing"

So "because it is growing at a rate of 40-60 per cent a year" or comes there "because of it's growing rate of 40-60 per cent a year"

and sentence 5 is in Article 5

"One of the good solutions is product placement. If you place a car, a mobile, sunglasses, a laptop -in fact anything- in a TV program or movie, people will see it. And of the like the program then they'll have a good feeling about the product. "

what exactly should jz in sentence 5? And how should I install that because or because of?

The article should refer to the sentence "it's (it is) growing at an amazing 40-60 per cent a year".

So you need "because it is growing at a rate of 40-60 per cent a year" With because of it should read "because of its (possessive pronoun) growth rate of 40-60 per cent a year"

The following video explains the difference between using because and because of:

Try sentence 5 yourself now and then set it here for checking and, if necessary, correction. The original text to which the exercise relates would also be nice.

"Because" means "because", "because of" means "because of".

Question 1: you can, but then also without "at an".

Second paragraph. With the variant only "because of its…"

To sentence 5: "And if they like…"

Otherwise I think the sentences are okay. I wouldn't include a "because" or "because of" there either.

The last sentence doesn't get any better if you turn it around (because some don't like to start with "Because"):

They ('ll) have a good feeling because they like the program (me).
