Predicting is a natural and important part of reading! Let's go through each statement.
A) The title tells us something key about the story; it is a phrase that helps us understand what the selection is about.
B) Descriptions allow us to create pictures in our minds and to infer or understand more of what is happening in the story and more of who the people are, etc. People are an important part of the reading, so knowing more about them is significant.
C) In life, we understand more than just the words that are said: we use gestures, facial expressions, our background and experiences, tone, and more to understand what is truly being communicated. The same is true in reading.
D) Active reading helps us to be engaged in what we are reading, so that we can get the most possible from it.
A, C, and D do not help making the reading more understandable or are not true. So, B must be true.
