The correct answer is 'A' i.e. this part of the sentence has an error.

Key Points

• The error lies in the use of the pronoun "myself" in part (A) of the sentence.

• Reflexive pronouns are used when the subject and the object of the verb are the same, which is not the case here.

Therefore, the correct answer is option 1.

Additional Information

• Option 2 (part B) - "did the entire": There is no error in this part as the verb "did" and the adjective "entire" are correctly used.
• Option 3 (part C) - "household jobs yesterday": This part of the sentence is grammatically correct and does not contain any errors.

The correct answer is 'To make someone laugh'.

Key Points

• The most appropriate word meaning of the given idiom is 'To make someone laugh'.
• Explanation: The idiom "crack someone up" means to make someone laugh uncontrollably or to cause amusement. It originated from the idea of causing someone to burst into laughter, often with the implication that the laughter is sudden and intense, like the sound of something cracking.
• For example, if someone tells a hilarious joke that makes another person laugh so hard that they can't stop, you could say, "That joke really cracked him up."
• The origin of the idiom is not definitively known, but it likely stems from the concept of "cracking" someone's composure or seriousness, replacing it with laughter. 

The correct answer is: The librarian asked her if she could return the books.

Key Points

• The sentence is in direct speech, which means it is a statement made by someone using their exact words.
• To convert the sentence to indirect speech, we need to change the tense of the verb and use reporting verbs like 'asked', 'told', 'requested', etc.
• In this case, the reporting verb is 'asked' and the tense of the verb 'can' changes to 'could'.
• The pronoun 'you' changes to 'she' as we are reporting what the librarian said to someone else.

Therefore, the correct answer is option 1.

Additional Information

• Option 2 - The librarian greeted her if she could return the books. (Incorrect - 'greeted' is not an appropriate reporting verb in this context)
• Option 3 - The librarian asked her that if she could return the books. (Incorrect - the word 'that' is not required and makes the sentence awkward)
• Option 4 - The librarian asked her that could she return her books. (Incorrect - the pronoun 'her' is not required and changes the meaning of the sentence)

The correct answer is 'Kuhu told her sister that she had brought a doll for her'.

Key Points

• The given sentence is in direct speech.
• Direct speech:- The reporting of speech by repeating the actual words of a speaker.
  • For example:- ‘I'm going,’ she said.
• We have to convert it into an indirect speech.
• Indirect speech:- Indirect speech is speech that tells you what someone said but does not use the person's actual words.
  • For example:- 'They said you didn't like it', 'I asked her what her plans were', and ' Citizens complained about the smoke'.
• In order to convert the given direct speech into an indirect speech, we have to follow some of the steps:-
• The reported verb said to present in the direct speech should be converted into told in an indirect speech.
• The inverted commas under which the reported speech has been written in the direct speech should be removed and in place of it that should be written in an indirect speech.
• The pronouns(I, you) used in the direct speech for Kuhu and her little sister should be converted into (she, her) in indirect speech.
• The main verb have present in direct speech should be converted into had in indirect speech as the reported verb is in past tense form.

Hence, the correct answer is option 3.

The correct answer is 'with important secret informations'.

Key Points

• The word 'information' is uncountable in English. We do not use it in the plural form ('informations').
• So, the correct phrase should be 'with important secret information'.
• Thus, the error is in the part 'with important secret informations'.

Therefore, the correct answer is Option 2.

The correct answer is 'The phone rang while I was doing the dishes.'

Key Points

• Let us explore the uses of the given options:
  • Either is used when referring to a choice between two options.
    • Example: Either one deserves to win.
  • ​We use but as an alternative to except (for). 
    • Example: I swear by Almighty God, to tell the truth, the whole truth and nothing but the truth.

    • Example: She cried because she failed the examination.

    • Example: I'll remember that film as long as I live.
  • We can put clauses with 'while' before or after the main clause.
  • We can use 'while' to talk about two longer events or activities happening at the same time.
    • Example: Lucy came into the room while he was waiting.
• Here, we are talking about two events "The phone rang" and "I was doing the dishes" which were happening simultaneously.
• Therefore, we need to use "while" to connect these two clauses.​

​​Correct sentence: The phone rang while I was doing the dishes.

The correct answer is "am."

Key Points

• In the given sentence, the present continuous tense (am writing) is not appropriate to describe a future action.
• The error is with the verb "am."
• It should be replaced with "will be" to make the sentence grammatically correct.
• Will Be is the future continuous tense form of “to be” and is used to express an ongoing action or state in the future. 
  • Example: I will be going to the gym tomorrow.
• Thus, the correct sentence should be "Tomorrow in the exam hall, I will be busy writing answers."

Hence, the correct answer is option 2.
