Q4: Sentence correction

Understanding the topic

The paper asks for five of the eight, so choose the five whose errors you can actually name rather than the five that look shortest.

(ii)

Printed: We cleaned all the kitchen while our parents were out to dinner.

Corrected: We cleaned the whole kitchen while our parents were out to dinner.

Rule: "All" does not modify a singular countable noun on its own. Use "the whole" or "all of the".

(iii)

Printed: If I'm stressed out about something, I tend to have problem to fall asleep.

Corrected: If I am stressed about something, I tend to have trouble falling asleep.

Rule: "Have trouble" takes a gerund, not an infinitive. "Problem" would also need an article, which is why "trouble" is the cleaner fix.

(iv)

Printed: If I will be in Lahore, I will contact to you.

Corrected: If I am in Lahore, I will contact you.

Rule: A first conditional takes the present simple after "if", never "will". "Contact" is transitive and needs no preposition.

(v)

Printed: The cultural globalization, it is a phenomenon that has been driven by technological advancements and economic integration, is a threat to local cultures.

Corrected: Cultural globalization, a phenomenon driven by technological advancement and economic integration, is a threat to local cultures.

Rule: An abstract noun used in a general sense takes no article, and an appositive should not carry its own subject and verb.

(vi)

Printed: The impact of cybertechnology on modern society is being studied by researchers, who has found that it has both positive and negative effects.

Corrected: The impact of cybertechnology on modern society is being studied by researchers, who have found that it has both positive and negative effects.

Rule: A relative pronoun takes its number from its antecedent. "Researchers" is plural, so the verb is "have".

The three not attempted

Sentence (i) has a dangling opening participle and a subject-verb disagreement. Sentence (vii) misuses the future perfect where the simple future is meant. Sentence (viii) is the worst of the eight, mixing "having been perpetuate" with a plural and singular mismatch, and is best left alone under time pressure.
