Answer: D)to introduce the textual evidence
Explanation: While it can be difficult at times to start sentences in order to express ideas or thoughts, sentence starters can come to the rescue as they are words and phrases to use at the start of sentences and thus provides a partial frame to begin. It serves to introduce the textual evidence (the point of analysis) within a text in order to complete a writing or discussion activity thus helping them build toward the ability to analyze and write about content without the use of the frames.
