What is an inference?


Writers of fiction often show their characters in action and allow them to speak for themselves. Readers then have the job of deciding what those actions and words mean and what they reveal about the characters, the events of the story and the message the author intends to send. In other words, readers must draw inferences about what they read. An inference in fiction is a reasonable conclusion or judgment about some element of a story based on the information given in the story and the reader's personal knowledge of how the world works.

a)

a reasonable conclusion or judgment about some element in a story

information contained in a story that leads a reader to the theme

You put these two pieces of the puzzle together in a logical way to produce a reasonable conclusion that supplies the missing piece of information or the answer to your question. Drawing an inference requires your background knowledge and information from the text?

a)

True

b)

False

44.

You draw many inferences in your everyday life?

You've just drawn an inference.

a)

True

b)

False

45.

Drawing an inference from a book follows the same process of drawing inferences in your everyday life?


Drawing Inferences Let's go back to your cat and apply the process for making an inference. At first, you might wonder what your cat is doing.

So you put those two pieces together in a logical way and correctly infer that your cat wants food.

True

False

The toothbrush as we know it today was not invented until 1938. However, early forms of the toothbrush have been in existence since 3000 BC. Ancient civilizations used a "chew stick," which was a thin twig with a frayed end. These 'chew sticks' were rubbed against the teeth. The bristle toothbrush, similar to the type used today, was not invented until 1498 in China. The bristles were actually the stiff, coarse hairs taken from the back of a hog's neck and attached to handles made of bone or bamboo. Boar bristles were used until 1938, when nylon bristles were introduced by Dupont de Nemours. The first nylon toothbrush was called Doctor West's Miracle Toothbrush. Later, Americans were influenced by the disciplined hygiene habits of soldiers from World War II. They became increasingly concerned with the practice of good oral hygiene and quickly adopted the nylon toothbrush. What can you infer about the nylon toothbrush?

a)

It was cheaper than previous toothbrushes.

b)

It worked better than any toothbrush before it.

c)

It was very popular when it was invented.
