B. Ne
Explanation: Question forms with modal verbs of probability (Might she be …?) are unusual. We usually use 'Do you think…?' instead.
A. She might be joking about it.
B. He must have caught a later train.
C. They can't have been trying very hard.
D. Do you think he might be Portuguese?
Explanation: The perfect infinitive is formed with have + past participle and expresses degrees of probability in the past. 'He must have caught a later train.' is a direct example of this. 'They can't have been trying very hard.' uses the continuous infinitive (have + been + -ing) which is also a form that expresses probability in the past, as mentioned in the section 'The continuous infinitive is formed with have + been + -ing. She must have been joking. They can't have been trying very hard.' 'She might be joking about it.' uses a present continuous infinitive, not a perfect infinitive for past probability. 'Do you think he might be Portuguese?' asks about present probability using 'Do you think' with a modal verb, not past probability with a perfect infinitive.

A. Ano
B. Ne
Explanation: The study materials define a noun phrase as 'a group of words including a noun', providing examples like 'a book' and 'my book'. The examples of continuous infinitives following modal verbs, such as 'must be joking', do not fit this definition.
A. It is exclusively a single noun.
B. It is a group of words that must contain a noun.
C. It is a group of words that describes an action.
D. It is a word that modifies a verb.
Explanation: The study materials define a noun phrase as 'a group of words including a noun'. Therefore, option 1, 'It is a group of words that must contain a noun', is the correct definition.
