Answer 1

Sentences have been converted from active to passive voice, with focus shifted from the subjects performing actions to the subjects being acted upon by adding a form of the 'be' verb and the past participle of the main verb.

Step-by-step explanation:

Active to Passive Voice Conversion-

When converting sentences from active voice to passive voice, you're changing the focus from the subject performing the action to the subject being acted upon. The form of 'be' verb along with the past participle of the main verb is used, and often a 'by [noun phrase]' is added or implied. Here are the requested sentences converted into passive voice:

1. He would be received with open arms by us.
2. Enough attention is not being paid to this issue by the international community.
3. Harry Potter's books are being read by many adults.
4. Alcohol can be sold in pubs (by them).
5. Calls are being placed and received by New Yorkers.
6. Plants are rarely eaten by great predators.
7. The journalists are being given a lot of information by the astronauts.
8. Dr Livingstone is going to be invited to participate in the project by us.
9. A new product has been introduced in Asia by American companies.
10. The driver was given a ticket by the traffic warden.
11. Their new record couldn't be released by Radiohead last December.
12. Instructions were never given to me (by them).
13. The number of deaths has been greatly reduced by medical advances.

Remember that sometimes passive voice is used when the doer of the action is unknown or when the focus is on the action itself rather than who is performing it.
