Explanation

The sentence uses a first conditional structure with "If + present tense", so the result clause should use "will" or simple present, not "would".

"Would" is used in second conditionals (with past tense in the "if" clause), so it's incorrect here with "treats".

Correct sentence: If a teacher treats students nicely, they will always listen to her.

Explanation

The correct verb form after "can" is the base form — it should be "walk", not "walked".

Correct sentence: "How can you walk long distances when you are unwell?"

Explanation

The article "a" before "child" is incorrect here because it's referring to his daughter, a specific person already mentioned.

Correct sentence: My friend has a sweet daughter, but the child often remains sick.

Explanation

"Speke" is a spelling error; the correct spelling is "speak".

Correct sentence: Although Saleem has lived in Lahore, he can't speak Punjabi well.

Explanation

After mustn't, we use the base form of the verb, not with 's'.

Correct sentence: We mustn't break the school furniture.

Explanation

The sentence uses future + conditional, so it needs the subjunctive form "were" instead of "was".

Correct sentence: I won't be able to join you if my baba were at home.

Explanation

The sentence is in passive voice and requires the past participle form of the verb.

"Feed" should be "fed" → Correct sentence: All the cows are fed by my younger brother.

Explanation

The verb "cook" should be in the past participle form because the sentence is in passive voice.

Correct form: "cooked".

Correct sentence: "Our food is always cooked by our mother."

Explanation

The correct phrase is "in spite of", not "in spite from".

"In spite of" means despite.

Correct sentence: "English became the official language for business in spite of the fact that the population was largely Chinese."

Explanation

The subject "cloud" is singular, so the verb must also be singular.

"Float" should be "floats" to agree with the singular subject.

Correct sentence: "I wandered lonely as a cloud that floats on high over hills and vales."
