The correct auxiliary verb to form a question in the past tense is 'did'. Therefore, 'Why did you break your promise?' is grammatically correct. 'Is' and 'done' do not fit the question structure, and 'None of these' is incorrect since option B is correct.

Both 'People' and 'Ransom' are nouns. 'People' is a noun referring to a group of human beings, while 'Ransom' is a noun referring to the sum of money demanded for the release of kidnapped individuals. 'Innocent' is an adjective describing the people. Given the options, 'Ransom' is also a correct noun, and since the question asks for a noun without further specification, 'Ransom' is a valid answer. However, 'People' is also a noun. The question is ambiguous as both A and B are nouns, but 'Ransom' is the more precise noun related to the context of kidnapping for ransom.

A 'commuter' is defined as a person who travels regularly between home and work or school, making option A the correct answer. The other options do not relate to the meaning of 'commuter'.

An appositive noun renames or identifies another noun next to it. In the sentence, 'singer' renames 'my brother' and is the appositive noun. However, option A 'The Singer' is incorrect because the sentence uses 'singer' without 'The'. Options B and C are not nouns, and D 'None of these' is correct since none of the options exactly match the appositive noun 'singer'.

Option A correctly uses the present perfect continuous tense with the appropriate preposition 'for' to indicate duration. The original sentence is grammatically incorrect and uses 'since' improperly with a duration. Options B, C, and D use incorrect prepositions for expressing duration.

The phrase 'I am not cut out for the banking job' means the person believes they are not suited or qualified for the banking job. None of the given options correctly express this meaning, so 'None of these' is the correct choice.

The sentence requires a past tense verb to complete the phrase 'He ___ urged all public sector to focus their activity.' None of the options 'Done,' 'Did,' or 'Has' fit correctly before 'urged.' The correct form would be 'He has urged' or 'He did urge,' but since 'Has' alone is incomplete and 'Did' is not followed by the base verb, none of the given options are correct. Therefore, 'None of these' is the best choice.

The word 'Ampror' is a misspelling of 'emperor,' which is the correct spelling of the word referring to a sovereign ruler of an empire. Options B and C are incorrect spellings, and D is not applicable since 'emperor' is the correct correction.

An abstract noun refers to an idea, quality, or state rather than a concrete object. 'Ideas' is an abstract noun because it represents a concept, while 'drawing' is a concrete noun (a physical activity or object), and 'their' is a pronoun.

The word 'extempore' means 'spoken or done without preparation,' which directly matches the description of 'a speech delivered without any preparation.' The other options do not fit this meaning.
