Which should readers use along with explicit information to make an inference?

A. The authors attitude about the topic
B. Their personal feelings about the topic
C. What the author states directly about the topic
D. What they already know about the topic

D. What they already know about the topic

The correct answer is D. What they already know about the topic. Readers can use their prior knowledge or background information about a topic to make inferences. By combining explicit information from the text with their existing knowledge, readers can draw logical conclusions or make educated guesses about the meaning or implications of the information provided.

Readers should use option C, which is what the author states directly about the topic, along with explicit information to make an inference.

To make an inference, readers need to analyze the given information and draw conclusions that are not explicitly stated. While options A and B may be relevant in other contexts, when it comes to making inferences, it is important to rely on objective evidence and information provided by the author. Option D, what readers already know about the topic, can certainly be helpful in forming a broader understanding, but it should not be the sole basis for making an inference.
