Explanation:
Adverbs modify <em>adjectives</em>, <em>verbs</em> and, <em>other adverbs</em>. In some cases, they can change the meaning of the words or in some others, they can add meaning. An effective way to spot an adverb within a sentence is to look for words ending in -<em>ly</em>. Besides, usually the adverb within that sentence answers a <em>when</em>, <em>where</em> or <em>how</em> question related to the word that is being affected. In our case:
<em>* The curious puppy </em><u><em>wagged</em></u><em> its tail </em><em>anxiously</em>.
The word "<em>anxiously"</em> is the adverb modifying the verb<em> "</em><em><u>wagged"</u></em><em>, </em>because it answers the question: <em>How</em><em> did the curious puppy </em><u><em>wage</em></u><em> its tail?</em> -The answer would be: <em>Anxiously</em>.
