Let's go through these questions one by one, selecting the correct item and providing an explanation for each choice:
1) We were waiting for the train ___ the platform.
Correct answer: c) at
Explanation: The correct preposition to use with "waiting" and a specific location such as a platform is "at." This preposition indicates the location where an action is taking place.
2) We usually have ___ breakfast at 9 o'clock.
Correct answer: d) -
Explanation: In English, when talking about meals such as breakfast, lunch, or dinner, it's common not to use an article. The sentence is referring to the general meal of breakfast, not a specific instance of a meal.
7) If they ___ to Kyiv, they will visit many museums.
Correct answer: c) go
Explanation: This sentence is a conditional type 1, where the condition is expressed using the simple present tense ("go"), and the result is expressed using "will" + verb ("will visit"). The correct form is "go" to match the plural subject "they."
8) I will dance if they ___ my favourite song.
Correct answer: c) play
Explanation: Similar to the previous example, this is another type 1 conditional sentence. The condition here should be in the simple present tense, which is "play" to agree with the plural subject "they."
9) Go to ___ kitchen and take some milk from the fridge.
Correct answer: d) the
Explanation: In this case, "the kitchen" is the correct phrase as it refers to a specific place within a house. The definite article "the" is used because the kitchen is a specific, defined place that the speaker and listener are aware of.
These explanations should clarify why each answer is correct based on the grammatical rules of English.
