1. The correct option is "is going to break". "Is going to" is used to talk about a future event that is already arranged or is expected to happen based on present evidence. In this case, the printer is making funny noises, which indicates that it will break in the future.

2. The correct option is "is giving". We use the present continuous tense (is giving) to talk about future arrangements or plans that have already been made or decided. Here, Mr Higgings has already made plans to give a demonstration of the new robot tomorrow evening.

3. The correct option is "will you call". When expressing future intentions or arrangements, we use "will" to talk about a decision made at the time of speaking or based on present evidence. In this case, the scanner isn't working, so the decision to call someone to fix it will be made in the future.

4. The correct option is "until I've installed". We use "until" to indicate the time up to which an action or event will continue. In this case, the action of downloading the file will continue until the installation of anti-virus software is completed.

5. The correct option is "am going to". We use "am going to" to talk about plans or intentions for the future that have already been decided or arranged. In this case, the speaker has already decided to go to bed early tonight.

6. The correct option is "will not be". We use "will" to make predictions or talk about future events that are not planned or arranged. In this case, the speaker is predicting that they will not be late tomorrow morning.

7. The correct option is "starts". We use the simple present tense (starts) to talk about future events that are part of a schedule or timetable. In this case, the aerobics class is part of a regular schedule and will start at 8 p.m.

11. The correct option is "will be watching". We use the present continuous tense (will be watching) to talk about future actions or events that will be in progress at a specific time in the future. In this case, at 15:45, she will be in the middle of watching TV.

12. The correct option is "will have gone". Similar to questions 9 and 10, "will have gone" is used to talk about completed actions or events that will happen before a specific future time. In this case, the subject will have completed going back home by 23:30.
