Grammar

The sentence "Don't go to the theatre ____________________" is an imperative (a command or suggestion) followed by a conditional clause.
Let's analyze the options: Option (1) "if you don't want to": This creates a grammatically correct and meaningful sentence: "Don't go to the theatre if you don't want to.
" This means: if you have no desire to go, then don't go.
The "to" at the end is an elliptical use of the infinitive ("to go" is implied).
Option (2) "if you want too": "Too" is an adverb meaning "also" or "excessively".
If it means "if you also want [something else]", it doesn't fit well.
If it's a typo for "if you want to", then it's grammatically correct ("Don't go to the theatre if you want to [go]").
However, this expresses a contradictory idea (don't go if you want to go), which is not typical advice unless there's a specific ironic context not provided.
Option (3) "if you did not wanted to": Incorrect grammar.
After "did not", the base form of the verb ("want") should be used: "if you did not want to".
Even if corrected, "if you did not want to [go]" is past tense, while the main clause "Don't go" is present imperative.
This tense mix is awkward.
Option (4) "if you wanting him too": Incorrect grammar ("wanting" as main verb in if-clause without auxiliary "are").
Also, "him too" doesn't logically connect to the first part of the sentence.
Option (1) "if you don't want to" is the most grammatically sound and semantically appropriate completion for the sentence.

Passive voice is formed using a form of the verb "to be" + past participle of the main verb.
The subject of the passive sentence is the recipient of the action.
Let's analyze the options: Option (1) "My parents regard as an ideal couple.
" - This sentence is grammatically awkward as written.
If it meant "My parents regard [them] as an ideal couple," it's active voice (subject "My parents" performs the action "regard").
If it meant "[They] are regarded by my parents as an ideal couple," it would be passive.
As written, it's active but incomplete.
Option (2) "I asked him to go.
" - Active voice.
Subject "I" performs the action "asked.
" Option (3) "Problems have to be confronted.
" - Passive voice.
- "to be confronted" consists of "to be" + past participle "confronted".
- The subject "Problems" is the recipient of the action of confronting.
The agent doing the confronting is not specified (or implied as "by us" or "by people").
- The active equivalent would be something like "We/People have to confront problems.
" Option (4) "The tree was striking by lightning.
" - This should be "The tree was struck by lightning" to be grammatically correct passive voice.
"was struck" is "be" (past tense) + past participle "struck".
If corrected, it would be passive.
As written "was striking", it's active past continuous (if it made sense, e.
g.
, "The tree was striking a pose").
Considering the options as given, option (3) is a clear and grammatically correct sentence in the passive voice.

The response "B: Yesterday" indicates that the event happened in the past.
Therefore, the question must be in the past tense.
Let's analyze the options for forming a question in the simple past tense: - The auxiliary verb for simple past tense questions (if no other auxiliary is present like 'was'/'were') is "did".
- When "did" is used, the main verb remains in its base form (infinitive without "to").
Option analysis: Option (1) "does he went": "does" is present tense auxiliary, "went" is past tense main verb.
Incorrect structure.
Option (2) "does he go": "does" is present tense auxiliary, "go" is base form.
Correct for simple present question, but the answer "Yesterday" requires past tense.
Option (3) "do he go": "do" is used with I/you/we/they.
For "he/she/it", "does" is used in present.
Also, this is present tense.
Option (4) "did he go": "did" is past tense auxiliary, "go" is base form of the main verb.
This is the correct structure for a simple past tense question.
The complete exchange: A: When did he go to Chennai? B: Yesterday.
This is grammatically correct and contextually appropriate.

The phrase "last year" indicates that the action took place in the past.
We need a verb form that expresses past obligation or necessity.
- (1) have to go: Present tense obligation ("We have to go now/regularly").
- (2) had to go: Past tense obligation ("We had to go yesterday/last year").
This fits the context of "last year.
" - (3) has to go: Present tense obligation, singular third person ("He/She/It has to go").
Does not agree with "We".
- (4) had to gone: Incorrect verb form.
After "had to", the base form of the verb ("go") is required, not the past participle ("gone").
The correct sentence is "We had to go for swimming lessons last year.
" This indicates a past necessity or requirement to attend swimming lessons.
This matches option (2).

This question is about collective nouns used for groups of specific things.
- A school of ships: "School" is a collective noun for fish, whales, dolphins, porpoises (e.
g.
, a school of fish).
Not used for ships.
- A fleet of ships: "Fleet" is the correct collective noun for a group of ships (especially warships, but also commercial vessels) operating together or under one command.
- A bundle of ships: "Bundle" is used for things tied or grouped together, like a bundle of sticks, a bundle of nerves, a bundle of laundry.
Not used for ships.
- A pack of ships: "Pack" is used for animals like wolves, dogs, hounds (a pack of wolves), or for items grouped together for carrying (a pack of cards, a backpack).
Not used for ships.
Therefore, the correct phrase is "A fleet of ships".
