TOEFL Reading: inference and rhetorical purpose practice

B2Reading40 questionsUpdated

Inference questions in TOEFL Reading ask what must be true given the passage; rhetorical purpose questions ask why the author put a sentence where it is. Both go one step beyond the words on the screen, and both are lost by candidates who take a bigger step than the text allows. These 40 items train the small, defensible move.

What this task tests

  • Whether you can draw a conclusion the passage supports without stating it.
  • Whether you can tell an inference from a guess based on what you already know.
  • Recognising the function of a sentence: example, contrast, exception, definition, evidence.
  • Reading the sentences either side of a highlighted line rather than the line alone.
  • Respecting hedges: some, often, may. An option that removes them is usually wrong.
  • Following contrast signals such as though, yet, despite and while.
  • Noticing when two sentences have to be combined to reach the answer.
  • Holding your nerve: the correct inference is often the least dramatic option.
  • Speed, because these are the slowest one-point items on the section.

How to do it

  1. Step 1:

    Read the stem for its verb

    Infer, suggest, imply and indicate mean the answer is not written down. Why and in order to mean the answer is a function, not a fact.

  2. Step 2:

    Go to the line, then widen

    Read the highlighted sentence, then the one before and the one after. Purpose is nearly always visible in the neighbours.

  3. Step 3:

    Name the function in your own words

    Say ‘this is an example of the claim above’ or ‘this is the exception’ before reading the options. Then choose the option that matches your label.

  4. Step 4:

    Take the smallest step

    Ask what the passage forces you to accept, not what it makes plausible. If an option needs one extra assumption, it is the wrong one.

  5. Step 5:

    Keep the hedge

    If the passage says some scholars, reject the option that says most or all. Matching the strength of the claim settles more items than any other check.

  6. Step 6:

    Test against the text, not the world

    You may know the topic. That knowledge is not evidence here, and it is the fastest route to a confident wrong answer.

  7. Step 7:

    Point to your line

    Before you confirm, name the sentence that makes the option safe. If you cannot name one, you are guessing.

  8. Step 8:

    Bank them until last

    Do the vocabulary and factual items for the passage first. Inference items reward the fuller picture you have by then, and they are the right place to spend the time you saved.

Mistakes that cost marks

  • Not thisChoosing ‘workers never read fiction’ from ‘the most requested titles were technical manuals’.

    ThisChoosing ‘workers borrowed mainly for practical reasons’.

    Most requested does not mean only requested; the option turns a comparison into an absolute.

  • Not thisAnswering a purpose question by describing what the sentence says.

    ThisDescribing what the sentence does.

    A correct summary of the content can still be the wrong answer: the question asks for the author’s reason for including it.

  • Not thisUsing background knowledge about wolves, paper or libraries.

    ThisUsing the passage only.

    Distractors are written to match what a well-read candidate expects, so outside knowledge points straight at them.

  • Not thisChoosing the option with the most striking claim.

    ThisChoosing the flattest defensible one.

    Academic passages are cautious, and so are their correct inferences.

  • Not thisReading only the highlighted sentence on a purpose item.

    ThisReading the sentence before it.

    The claim a detail supports is usually in the previous sentence, which is why the detail is where it is.

  • Not thisAnswering ‘to entertain the reader’.

    ThisAnswering with a function such as illustrate, contrast or define.

    TOEFL passages are expository. Entertainment is not something the writing is doing.

Passage D: “The first public libraries in the mill towns were paid for by the mill owners, who set opening hours to begin an hour after the evening whistle. Borrowing records show that the most requested titles were technical manuals rather than fiction.” It can be inferred from Passage D that the owners

2Complete with one verb (third person) beginning with i.

An inference question asks what the passage strongly , not what it states.
True or false about inference questions?
  • A correct inference must be supported by something in the passage.
  • A correct inference is written word for word somewhere in the passage.
  • An inference may rest on two sentences read together.

Passage E: “Wolves returned to the valley in 1997. Within a decade, willow and aspen along the streambanks had recovered and beaver colonies, absent for forty years, reappeared. Elk, the wolves’ main prey, had previously browsed the young shoots year round.” It can be inferred that the willows recovered because

5Complete with one verb beginning with m.

Rhetorical purpose questions usually begin “Why does the author …?”
Passage F: “Paper made from wood pulp turns brittle within a century because the process leaves acid in the fiber. Books printed on rag paper in the 1600s can still be handled safely, while many printed around 1900 cannot be opened at all.” The author mentions books printed in the 1600s in order to

7Complete with one noun beginning with r.

The answer to a purpose question describes the author’s for including a detail, not the detail itself.

8In one sentence, explain the difference between a factual question and an inference question.

Which option is most likely to be a wrong inference?

10Complete with one superlative adjective beginning with s.

A safe inference is the step beyond the text, not the most interesting one.

Frequently asked questions

How do I stop over-inferring?

Before you confirm an option, say out loud which sentence forces it. If your justification contains the words “probably” or “it makes sense that”, you have taken a step the passage did not license.

Are purpose questions really about the author?

About the writing, not the person. You are describing the job a sentence does in its paragraph: giving an example, marking an exception, defining a term, supporting the claim above it.

Why do wrong options often sound sensible?

Because they are written to match what an informed reader expects about wolves, libraries or paper. Plausibility in the world is not support in the text, and that gap is what the item is measuring.

Do these questions take longer than the others?

Yes, and they should. Answer the vocabulary and factual items on a passage first; by the time you reach the inference items you know the text better and can afford the extra half minute each.

What if the highlighted sentence is the first in a paragraph?

Then read the last sentence of the paragraph before it. A sentence in that position usually links back to what has just been established or announces what the paragraph will do.
