The format
You get two sets of Interactive Reading per test, each based on a single passage. Everyone gets one 7-minute set and one 8-minute set. Each set contains six questions, and they always arrive in the same order.
The two passages are of different kinds: one is a story (narrative) and one gives facts or information (expository). Passages are short — roughly 70 to 140 words, depending on how hard the set is.
It feeds your Reading score, and therefore the Comprehension and Literacy subscores. Everything is scored right-or-wrong except Highlight the Answer, which gives partial credit.
The six questions, in order
| # | Question | What you do | Scored |
|---|---|---|---|
| 1 | Complete the Sentences | Fill in missing words in the first half of the text. | Right / wrong |
| 2 | Complete the Passage | The second half appears. One sentence is missing between the halves — choose the one that joins them. | Right / wrong |
| 3–4 | Highlight the Answer (×2) | Select the part of the text that answers a question. | Partial credit |
| 5 | Identify the Idea | Choose the main idea of the whole text. | Right / wrong |
| 6 | Title the Passage | Choose the best title for the whole text. | Right / wrong |
Notice what that order does. Question 1 is about individual words. Question 2 is about a sentence. Questions 3 and 4 are about where information lives in the passage. Questions 5 and 6 are about the whole text.
The questions zoom out steadily, and they all use the same passage. So the set is not six separate tests of your reading — it is a ladder, and every rung teaches you something you need for the next one. Duolingo's own tip is exactly this: use what you learn in the early questions to help with the later ones.
The clock is shared, and this is what people fail
There is one timer for all six questions — 7 minutes, or 8 in the longer set. Not one per question.
Questions 5 and 6 are the ones you should be most likely to get right, because by the time you reach them you have read the passage four times. Arriving at them with no time is the most expensive thing that can happen in this task, and it is entirely self-inflicted.
A workable budget for a 7-minute set:
| Question | Rough budget |
|---|---|
| Complete the Sentences | ~90 sec |
| Complete the Passage | ~90 sec |
| Highlight the Answer ×2 | ~2 min |
| Identify the Idea + Title the Passage | ~2 min — and these should feel easy |
If a gap will not come, choose the most plausible option and move on. One uncertain answer costs you one mark. Running out of time costs you two.
What each question is actually testing
Complete the Sentences
The missing words are usually recoverable from grammar and collocation, not just meaning. If the gap follows a significant …, you need a noun. If it follows she … quickly, you need a verb. Narrow by form first, then choose by meaning — that eliminates most of the options before you have thought about the passage at all.
Complete the Passage
You are choosing the sentence that joins the two halves. So the correct answer is defined by what is on both sides of it — it has to follow from the sentence before and lead into the sentence after.
The wrong options are usually true statements about the topic. That is what makes them tempting. Read the sentence immediately before the gap and the one immediately after, and ask which option makes those two sit together — not which option is a good sentence.
Highlight the Answer
The only partial-credit question in the set, which means selecting roughly the right region still earns something. Do not leave it blank because you are unsure of the exact boundary.
Highlight the span that actually answers the question, and no more. Selecting a whole paragraph when one clause is the answer is not a safe hedge — precision is what is being measured.
Identify the Idea, and Title the Passage
These two are the same question at different sizes, and both official tips warn about the same trap: do not choose an option that is only about one small part of the text.
The distractors are typically accurate details lifted from the passage. They are true, they are in the text, and they are wrong — because the question asks what the whole text is about. A good test: could this be the main idea if the passage stopped after the second sentence? If so, it is a detail.
And solve them in order. If you have settled the main idea in question 5, the title in question 6 is nearly free — which is why Duolingo tells you to use one for the other.
What to practise
The skill this task rewards is not reading speed. Passages are short — 70 to 140 words — and you are given the text over and over. It rewards reading a short text accurately under a clock, and one specific habit above all: being able to state, in one sentence, what a paragraph was about.
- Read short factual texts and summarise each in a single sentence. News-in-brief items, encyclopedia openings, product descriptions. If your sentence contains a detail rather than the point, that is the exact error the last two questions punish.
- Practise separating the main idea from a true detail, since that distinction is the whole of questions 5 and 6.
- Practise with a timer. The task is not hard; the budget is. Reading well with 90 seconds on the clock is a different skill from reading well.
- Read both kinds of text, because you will get one of each: a story and an information text. They fail people differently — narratives hide the point, information texts bury it under facts.
Frequently asked questions
How long is DET Interactive Reading?
You get two sets per test — one with a 7-minute limit and one with 8 minutes — and each set contains six questions on a single passage. The timer is shared across all six questions in the set, not per question, which is why budgeting your time matters more than reading quickly.
What are the six Interactive Reading questions?
They always come in the same order: Complete the Sentences, Complete the Passage, two Highlight the Answer questions, Identify the Idea, and Title the Passage. They zoom out steadily, from individual words to the meaning of the whole text, and they all use the same passage — so each question teaches you something you need for the next.
Which Interactive Reading questions give partial credit?
Highlight the Answer is the only one — it is scored 0 to 1 on partial credit, so selecting roughly the right region of the text still earns marks. The other five questions are scored right or wrong. That means you should never leave a Highlight question blank because you are unsure of the exact boundary.
How do I choose the main idea or the title?
Rule out the options that are only about one part of the text. The distractors are usually accurate details taken from the passage — they are true, and they are wrong, because the question asks what the whole text is about. A useful check: if the statement could still be the main idea after only two sentences of the passage, it is a detail, not the idea.
What kinds of passages appear in DET Interactive Reading?
Each test gives you two: one narrative (a story) and one expository text (facts or information). Passages are short — roughly 70 to 140 words depending on the difficulty of the set. They fail people in different ways: narratives tend to hide the point, and information texts tend to bury it under details.
