Is this sentence not in direct support of the first sentence? Hence, first sentence should be the main idea.
Hi,
Sorry for the really late reply to this, we had to discuss this one because we thought you made a good point.
That’s correct, the second sentence is a specific example of the first one.
The rest of this passage is about this specific example. not the general idea from the first sentence, so we fell that this fits the main idea more.
Does that make sense?
