Could is the past tense form of can.

Can is a modal verb. Modal verbs are auxiliary verbs that express possibility, permission, ability, etc. They are always followed by a base form of a verb (e.g., "can go," "can sing," "can eat").

Therefore, the correct answer is A: can.

Option B, "can be," is incorrect because "can be" is a present tense form expressing possibility or potential. It's not the past tense of "could."

Option C, "cannot," is the negative form of "can," but it is still present tense.

Option D, "cloud," is completely unrelated and grammatically incorrect.

Cut this apple with that knife.

The preposition "with" is used to indicate the instrument or tool used to perform an action. In this case, the knife is the tool used to cut the apple, so "with" is the correct choice.

Option A: by is incorrect because it refers to the agent performing the action, not the tool used.

Option C: in is incorrect because it suggests location or direction rather than the tool used to perform the action.

Option D: into is incorrect because it indicates the result or direction of an action (e.g., cut into pieces), but here we are focusing on the tool used to cut the apple.

Conclusion: The correct answer is Option B: with, as it properly indicates the use of a knife as the tool to cut the apple.

The question asks about the correct preposition to use with "foot" when referring to the mode of transportation.
Preposition: A preposition is a word that shows the relationship between a noun or pronoun and another word in the sentence. It indicates things like location, time, direction, or manner.
On foot: This phrase means "walking." It is a fixed expression in English, meaning we don't use other prepositions with "foot" in this context.
Therefore, the correct answer is A: on.
Let's look at why the other options are incorrect:
B: by – "By foot" is grammatically correct in some contexts, but it is less common than "on foot" and sounds slightly unnatural to many native speakers when talking about regular travel to school. "By" is typically used with other means of transportation (e.g., by bus, by car, by train).
C: with – "With foot" is grammatically incorrect in this context. "With" indicates accompaniment or the instrument used to perform an action.
D: walking – "Walking" is a verb, not a preposition. While you could say "Do you always go to school walking?", it's grammatically correct but less concise and common than "Do you always go to school on foot?".

In the given sentence, "Do you think that flying an airplane is a..." the correct word to complete the sentence is an adjective that describes the experience. The appropriate choice is terrifying, making the complete sentence, "Do you think that flying an airplane is a terrifying experience?"

This question tests your understanding of verb tenses, specifically the present continuous tense.

Present Continuous Tense: The present continuous tense is used to describe actions happening now, at this moment in time. It's formed using the present tense of the verb "to be" (am, is, are) + the present participle (verb + -ing).

The sentence "Don't disturb the principal" indicates that something is happening at the present moment. The following clause needs a verb that reflects this ongoing action. "Is sleeping" perfectly conveys this: the principal is currently in the act of sleeping.

Why other options are incorrect:
A. sleeping: This is the present participle, but it lacks the auxiliary verb ("is") needed to form the present continuous tense. It would be grammatically incorrect and doesn't convey the ongoing action.
C. sleeps: This is the simple present tense, indicating a habitual action. While the principal might habitually sleep in his chamber, the sentence implies he's doing so *right now*.
D. slept: This is the simple past tense, referring to an action completed in the past. It doesn't fit the context of the sentence, which describes a present action.

Therefore, only "is sleeping" accurately reflects the ongoing action of the principal sleeping at the moment of speaking.

In this sentence, the phrase "last week" indicates a specific point in time in the past. When we want to express an action that started in the past and continues up to the present moment, we use the present perfect tense along with the preposition "since."

Therefore, the correct completion of the sentence would be:
"Eagle has been flying in the sky since last week."

Options B, C, and D are incorrect because:
Option B: "for" is used to indicate the duration of time, not the starting point of an action.
Option C: "over" is used to indicate movement across or above something, but it does not convey the correct meaning in this context.
Option D: "before" is used to refer to actions or events that happened prior to a specific point in time, which is not appropriate here.

Therefore, the correct choice to complete the sentence is Option A: since.
