I looked this question up and found the underlined word is "declaration" and that it is supposed to be used as a verb in the new sentence.
Answer:
After reframing the sentence, we have:
The collector declared the local holiday.
Explanation:
The noun "declaration" is formed by adding the suffix -ation to the verb "declare". To use the verb in the sentence, we will need to make quite a few changes. The simplest way to do it is by using the active voice, which makes "collector" the new subject and demands the use of a verb to express the action of declaring. With that in mind, we can reframe the sentence in the following manner:
The collector declared the local holiday.
The verb "declared" is in the past form because the original sentence also used a past structure.
