The proper usage of the adverb "moreover"

[Tinagik]

Hello. I was wondering if Mister Macawber could help me with this, or someone else, if possible. This from a CPE Reading Test. Here is part of the text.:

"Sometimes it seems that no matter how many possessions you have, you never feel secure. While it is reasonable to have a basic nesting instinct and create a home which meets your needs, there is a point where the motivation for acquiring things gets out of control. Modern advertising is 2)... deliberately designed to play on our insecurities. 'If you don't have one of these you will be a lesser human being' is one of the consistent underlying messages"

The correct answer in my teacher's manual is: B) moreover

The other options are A)nonetheless C)thereby and D)whatever

I was wondering if "thereby" would make sense, or would it mean "as a consequence". Do we not choose this word because we are not stating a cause and effect....a reason for something occurring?...or are we say this? Is "moreover" correct because we are adding information, because we're talking about modern advertising affecting us in another way? To me, it seems like both "thereby" and "moreover" make sense!

I am a bit confused. :? I think that I need to go to bed in order to think more clearly. If you could explain the reason for the correct answer and the reason we exclude the other option, I would really appreciate it.

Thank you, Tina :)

Hi,

Let's look at the choice: 'nonetheless' usually starts another idea whereby you have to bear this new idea in mind when you set it against the first point/idea. 'Thereby' suggests 'in this way'. 'Whatever' is used to suggest 'it doesn't really matter'. 'Moreover' suggests that you are about to give an additional reason, which is appropriate here because the writer wants us to know something more about the effect of 'modern advertising.
