Answer:
Only sentences 1 through 3 need correction when it comes to parallel structures:
1. We expected to be disappointed and to reject the proposal.
2. Etiquette is important in social life and in business too.
3. Do you prefer organizing conferences, entering data, or balancing the budget?
Step-by-step explanation:
Parallelism consists of repeating the same grammatical structure in a sentence so that it sounds better. It also helps organize ideas, which makes them easier to understand.
Let's take sentence 1 as an example:
1. We expected to be disappointed and that we would reject the proposal.
The speaker of the sentence is listing what they expected. Two things were expected by them, but notice how different they sound:
- to be disappointed;
- that we would reject the proposal.
The things have completely different structures. One way to make them similar is to change the second one so that it uses the same structure as the first one:
- to be disappointed;
- to reject the proposal.
See how it sounds better and they are the same? Now, let's apply it to the sentence:
1. We expected to be disappointed and to reject the proposal.
