I have a few more doubts about a few sentences. Thank you.

1) He denied robbing (instead of stealing?) the money.
2) I couldn't do anything but copying the Maths test (instead of "cheating during/in the Maths test).
3) On walking in front of her room (instead of "On passing by her room"), I saw her studying (is "study" possible?)
4) He admitted /confessed TO stealing (is "to" necessary? Is it a mistake if you omit it?)
5) I finished the homework/my homework/homework (Which are correct?)

1) He denied stealing the money.

(He would rob the person or rob the house, but steal the goods.)

2) I couldn't do anything but copying the Maths test (instead of "cheating during/in the Maths test).
("copying" is OK, but "cheating" is better, more precise.)

3) On walking in front of her room (instead of "On passing by her room"), I saw her studying (is "study" possible?)
("walking by her room" or "passing by her room" -- both work; "studying" is best.)

4) He admitted /confessed TO stealing (is "to" necessary? Is it a mistake if you omit it?)
(The sentence reads best if you keep "to" in the sentence.)

5) I finished the homework/my homework/homework (Which are correct?)
("my homework" or "the homework" are best.)

1) In the sentence "He denied robbing the money," the word "rob" is commonly used to describe taking something by force or threat. On the other hand, "steal" refers to taking something without permission. Both words can be used in this context, so both "robbing" and "stealing" are correct. However, there may be a subtle difference in meaning. "Robbing" can suggest a more forceful act, whereas "stealing" might imply a more surreptitious or secretive action.

To find the answer to this doubt, you can consult a dictionary or thesaurus to understand the differences between "rob" and "steal." You can also refer to grammar resources or style guides for guidance on the correct usage and connotations of these words.

2) In the sentence "I couldn't do anything but copying the Maths test," the phrase "but copying" suggests a limitation or lack of alternatives. However, the word "copying" is not the most accurate choice here. Instead, you could use "cheating during the Maths test" or "cheating in the Maths test" to convey the intended meaning.

To clarify this doubt, you can review the definitions and synonyms of "copying" and "cheating" in a dictionary or use a thesaurus to find alternative words that accurately express the meaning you want to convey.

3) The sentence "On walking in front of her room, I saw her studying" is grammatically correct. However, you mentioned the alternative phrase "On passing by her room". Both phrases convey similar meanings, but "On walking in front of her room" suggests a deliberate act of going near her room, whereas "On passing by her room" implies a more incidental encounter.

Regarding the verb choice, "studying" is appropriate in this context because it refers to the action of engaging in academic activities. However, additional context would be needed to determine if "study" on its own is suitable.

To clarify this doubt, you can consult a dictionary to understand the meanings and usages of "walking in front" and "passing by." Additionally, you can review grammar resources to learn about verb forms and their appropriate usage.

4) The sentence "He admitted/confessed to stealing" is grammatically correct. In this case, the preposition "to" is necessary because it is used to indicate the action that is being admitted or confessed. Removing the preposition, for example, by saying "He admitted/confessed stealing," changes the structure and meaning of the sentence.

To confirm this doubt, you can consult grammar resources or style guides that provide information about prepositions and their usage with certain verbs. Alternatively, you can also search for examples or references to "admit" or "confess" in context to see how they are typically used.

5) All three options, "I finished the homework," "I finished my homework," and "I finished homework," are correct. The choice depends on the intended meaning and context.

- "I finished the homework": This implies a specific set of homework that was previously mentioned or is understood from the context.
- "I finished my homework": This indicates that the speaker completed their own assigned homework.
- "I finished homework": This indicates the completion of homework without specifying any particular set or ownership.

To clarify this doubt, you can refer to grammar resources or style guides that explain different uses of articles (like "the") or possessive pronouns (like "my"). Additionally, considering the context of the sentence will help determine which version best fits the intended meaning.
