1. The sentence "Paste the wall with paper." is not grammatically correct. To correct it and make it more clear, you could say "Paste the paper on the wall." This way, the action of pasting is being done to the paper instead of the wall.

2. and 3. Both sentences "The nurse mixed him a bottle of medicine." and "The nurse mixed a bottle of medicine for him." are grammatically correct. They have a slightly different emphasis and word order, but both convey the same meaning. The first sentence emphasizes that the nurse mixed the medicine for him, whereas the second sentence emphasizes that a bottle of medicine was mixed for him by the nurse.

4. and 5. Both sentences "The Sahara desert stretches across North Africa." and "The Sahara desert stretches across Northern Africa." are grammatically correct. However, "North Africa" is more commonly used and accepted. While "Northern Africa" is technically correct, it is not as commonly used in reference to the Sahara desert.

6, 7, and 8. The three sentences "He is a good fellow.", "He is a good guy.", and "He is a good man/boy." convey similar meanings but have slightly different connotations.

- "He is a good fellow." is a relatively informal way to say that someone is a good and reliable person, usually with a sense of camaraderie or friendship.

- "He is a good guy." is also informal but can be used to describe someone who is trustworthy, kind, and generally likable.

- "He is a good man/boy." is a more formal way to express that someone is of good character. It tends to be more commonly used in formal or serious contexts.

Overall, these sentences are similar in meaning, but the specific choice of words can convey different levels of formality or personal connection.
