1. The correct answer is nevertheless. Coordinate ideas are those that are equally important in a sentence - you cannot say that one is more important than the other. If you want to show contrast between them, you would choose the joiner nevertheless, which basically means <em>however. </em> 2. The correct answer is therefore. The joiner therefore shows us a particular result. So, something happened, and therefore something else happened as a result of the first event. Therefore means the same as consequently (which implies a consequence, or a result), as well as hence, thus, accordingly, etc.
The answers of the following are: 1. The joiner that shows a contrast between coordinate ideas is: Nevertheless = In other words, it also means "however". 2. The joiner that shows a result between coordinate ideas is: Therefore. In other words, it also means "as a result", or "consequently".
