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, "these three days", "their efforts to wipe away" and "each decoration" are all noun phrases because they have nouns as their heads ("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, in "have been celebrating" and "are considered", "celebrating" and "considered" are the main verbs.
