Inferences in Reading
Below is a sentence you saw in the chapter “Vocabulary in Context.”
Many of us have ambivalent feelings about our politicians, admiring them but also distrusting them.
That sentence does not tell us the meaning of ambivalent, but it does suggest that ambivalent involves both positive and negative feelings.
See page 274 in textbook.
Thus you can infer from this sentence that ambivalent feelings probably means “mixed feelings,” and you’d be correct.

A sociology professor wrote on the board, “A woman without her man is nothing” and, with a smile, asked students to punctuate the sentence correctly.

A. The professor did not believe students could punctuate the words correctly.

B. The professor knew there was more than one way to punctuate the words correctly.
Since the professor chose the particular sentence and smiled while writing the words, we can conclude that the professor was aware of more than one punctuation possibility.
Therefore, this is a logical inference.

A. The professor did not believe students could punctuate the words correctly.
Nothing in the passage implies that the professor doubted students’ ability to punctuate the words correctly.
This is not a logical inference.

C. The professor is not a good teacher.

D. Gender differences caused students to read and punctuate the

Male and female students had very different responses to the sentence. Gender was the only apparent difference among the students, so we can conclude that it caused the different responses.
This is a logical inference.

There is no suggestion in the passage that the professor is a poor teacher. In fact, the professor has chosen a dramatic way to suggest that each sex sees the world from its own point of view.
C. The professor is not a good teacher.

Now read this passage and consider the inferences.
A famous psychology experiment conducted by Dr. John B. Watson demonstrates that people, like animals, can be conditioned—trained to respond in
a particular way to certain stimulations. Watson gave an eleven-month-old baby named Albert a soft, furry white rat. Each time Albert tried to stroke the rat, Dr. Watson hit a metal bar with a hammer. Before long, Albert was afraid not only of white rats but also of white rabbits, white dogs, and white fur coats. He even screamed at the sight of a Santa Claus mask.

A. Dr. Watson did not like small children.
See page 276 in textbook.
B. Before the experiment, Albert was not afraid of white rats.
Because Albert tried to pet the rat, it is fair to assume that he wasn’t frightened of the animal.
This is a logical inference.

We might certainly question the way the baby was used, but the passage doesn’t give enough information for us to infer logically that Watson did not like small children.
A. Dr. Watson did not like small children.

This is not a logical inference.

Since the noise is what made Albert afraid of the rat, we have to infer that he was afraid of the noise.
C. Albert was afraid of unexpected loud noises.
In addition, experience tells us that babies are likely to be frightened of unexpected loud noises.

A. The work force of 1900 was very different from the work force of today.
