Answer:
d. Joe saw that his sleeping bag was soaked, and he rolled to the other side of the tent.
Step-by-step explanation:
Inferences are conclusions one makes based on logic or evidence. One must infer something if there is missing context, information, descriptions, et cetera. With that being said, let's analyze each sentence to see if we would need to infer something about the sentence due to missing context, information, or descriptions to understand what happened, or what is happening.
Choice A: "The snow was coming down hard, but inside our house it was warm." Choice A lays out all the information needed to grasp a basic understanding of what happened, and why it has happened. We know that snow is cold, and it is mentioned that the house is warm. So we know that they went in the house because it was cold (because of the snow), and it was warm inside; therefore, no inference is needed.
Choice B: "The bike looked new -- it had shiny handlebars and a smooth black seat." In this sentence, we're told the bike "looked new." If that statement wasn't followed with a description, we would have to infer why the bike "looked new," but we don't; therefore, no inference is needed.
Choice C: "Tim's sister was a little shorter than Tim, but had the same soft brown eyes." With this sentence, we can understand that Tim must be taller than his sister since the sentence says she is shorter than him. If Tim wasn't used as a comparison, we would have to infer exactly how short Tim's sister is, but we don't; therefore, no inference is needed.
Choice D: "Joe saw that his sleeping bag was soaked, and he rolled to the other side of the tent." With this sentence, we are told Joe's sleeping bag was soaked, and Joe rolled to the other side of the tent. We have to ask ourselves; "Why is Joe's sleeping bag soaked?" If we were given an explanation as to why his sleeping bag was soaked, or what is was soaked with, we could better understand what has happened, but we aren't given one; therefore, we'd have to make an inference.
