Explanation:
A phrase is a group of words that express a concept and is used as a unit within a sentence. Eight common types of phrases are: noun, verb, gerund, infinitive, appositive, participial, prepositional, and absolute
A clause is any noun phrase plus a verb; they can be sentences, but they don't always have to be.
Example: He is sleeping on the bed. The first part of the sentence “He is sleeping” is a clause because it has a subject and a verb. On the other hand, the remaining part of sentence, 'on the bed' is a phrase because it lacks both the subject and the verb.
A "popular press source" in general refers to any news publication, either on paper or online, that has a wide circulation and is popular. Although this doesn't always mean that it is reputable.
