Explanation
The given sentence contains two verbs: practice and learn. Both verbs indicate actions being performed by the subject (they). The verb "practice" shows the action of practicing dancing, while the verb "learn" shows the action of acquiring knowledge in English. Therefore, there are two verbs in the sentence.

Explanation
Adjectives can appear before a noun or after the verb "to be" in a sentence. When an adjective appears before a noun, it is used to describe or modify that noun. For example, in the sentence "The red car is fast," the adjective "red" appears before the noun "car" to describe its color. On the other hand, when an adjective appears after the verb "to be," it is used to describe the subject of the sentence. For example, in the sentence "She is happy," the adjective "happy" appears after the verb "is" to describe the subject "she." Therefore, both options B and C are correct.
