Answer 1

I was surprised that Kate wasn’t at the morning yesterday. She ___ about it.

d)might not have known.

Модальный глагол might + Perfect Infinitive указывает на выражение неуверенности в уже произошедшем действии.

Answer 2

The correct answer is d) might not have known.

Explanation: The sentence "I was surprised that Kate wasn't at the morning yesterday" suggests that the speaker was surprised by Kate's absence. To express this surprise, we need to use the past tense and a modal verb to indicate uncertainty or possibility.

In this case, we can use the modal verb "might" to express uncertainty about Kate's knowledge or awareness of the morning event. Since the event happened in the past, we need to use the perfect tense to indicate that the action (not knowing) happened before the past event (the morning yesterday). Therefore, the correct form is "might not have known."

Let's break down the options and see why they are incorrect:

a) may not know - This option is incorrect because it uses the present tense "may not know" instead of the past tense.

b) may not have knew - This option is incorrect because it uses the incorrect past tense form "have knew" instead of "have known."

c) might not knew - This option is incorrect because it uses the incorrect past tense form "not knew" instead of "not known."

d) might not have known - This is the correct answer. It uses the past tense form "have known" correctly with the modal verb "might."

To summarize, the correct answer is d) might not have known.
