Answer: The noun phrases are "These three days", "their efforts to wipe away" and "Each decoration", while the verb phrases are "have been celebrating" and "are considered".
Explanation: A noun phrase is a group of words that includes a noun, which acts as the head. The noun is modified by other word classes, such as adjectives or determiners. For instance, <u>"these three days", "their efforts to wipe away" and "each decoration" are all noun phrases because they have nouns as their heads</u> ("days", "efforts" and "decoration" respectively). The nouns in these phrases have been premodified and postmodified. In contrast, a verb phrase contains an auxiliary verb and a main verb. For example,<u> in "have been celebrating" and "are considered", "celebrating" and "considered" are the main verbs. </u>
