Final answer:
The statement 'The weather bureau uses balloons to determine the temperature aloft' is False regarding the presence of an infinitive or infinitive phrase because it does not contain the word 'to' followed by a verb, which constitutes an infinitive phrase.
Step-by-step explanation:
The phrase "The weather bureau uses balloons to determine the temperature aloft" does not contain an infinitive or infinitive phrase. An infinitive is the base form of a verb preceded by the word to. For example, in the sentence 'To determine the temperature, the weather bureau uses balloons,' 'to determine' is an infinitive phrase functioning as the subject. However, in the given phrase, there is no word to followed by a verb form, which means there is no infinitive or infinitive phrase present. Therefore, the correct answer to whether the statement contains an infinitive or infinitive phrase is False.
