Final answer:
To complete the sentences, provide an action or decision for absolute freedom and state your opposition against something. When a teacher asks for your absolute attention, you need to stop what you are doing and listen fully. 'Wholly' is not a synonym for 'absolutely'.
Step-by-step explanation:
In the first sentence, to complete the sentence 'If I had absolute freedom, I would', you would need to provide an action or a decision that you would make if you had complete freedom. For example, you could say 'If I had absolute freedom, I would travel the world.'
In the second sentence, to complete the phrase 'I am absolutely against-', you would need to state your strong opposition to something. For example, you could say 'I am absolutely against animal cruelty because it is wrong and harmful.'
To answer the second part of the question, when a teacher asks for your absolute attention, you need to stop what you are doing and pay full attention to the teacher.
The word 'wholly' is not a synonym for absolutely. Synonyms for absolutely include 'finally', 'entirely', and 'completely'.
