The word "had" needs to be added to the sentence so that it displays the information properly. This is because "had" is the past tense of the verb "have" and is used to indicate that an action occurred before another action in the past. In this case, adding "had" before "booked" clarifies that Dad booked the tickets before he collected them.

The comma is placed after the introductory phrase "Full of enthusiasm" to separate it from the main clause "the children entered the room at the start of their lesson." This helps to clarify the sentence structure and indicate that the phrase is providing additional information about the subject of the sentence.

Even though is the correct answer because it is used to introduce a subordinate clause that presents a contrast or contradiction to the main clause. It indicates that despite something being true or happening, there is still another fact or condition that is also relevant. The other options, such as "in addition," "furthermore," and "otherwise," do not serve the same purpose of introducing a subordinate clause that presents a contrast.

The word "shouldn't" in the sentence "shouldn't you" is a contraction of "should not" and indicates a suggestion or expectation. The word "you" is the subject of the sentence, indicating that the question is directed towards the listener. Together, these words form an interrogative sentence structure, making the sentence a question.

The relative clause in this sentence is "that was parked outside the shop." A relative clause is a type of subordinate clause that provides additional information about a noun or pronoun in the main clause. In this case, the relative clause is modifying an unspecified noun and giving more details about something that was parked outside the shop.

The sentence "Before we left, we turned the lights off" can be rewritten as "Before we left, we turned off the lights." Both sentences have the same meaning and structure, but the second sentence begins with the adverbial phrase "Before we left."

The determiners in the sentence are "much," "the," and "a." Determiners are words that come before nouns and provide information about quantity, ownership, or specificity. In this sentence, "much" is a determiner that indicates a large quantity, "the" is a determiner that specifies a particular noun, and "a" is a determiner that indicates an indefinite noun.

The correct answer is "The cake was lovely – delicious, in fact – so I had another slice." This sentence correctly uses dashes to set off the phrase "delicious, in fact" as an interrupter. The commas are also used correctly to separate the adjectives "lovely" and "delicious."

Based on the given options, the event that is most likely to happen is "She will buy some new shoes today." This is because the statement is in the future tense and expresses a specific action that can be easily accomplished within a day. The other options involve possibilities or suggestions, which may or may not occur.

The correct answer is "were" because it is used in the subjunctive mood to express hypothetical or unreal situations. In this case, the sentence is likely referring to a hypothetical condition or possibility, which requires the use of "were" instead of "was."
