What Is the Duolingo English Test Fill in the Blank Question?

The Duolingo English Test fill in the blank (“Interactive Reading: Fill in the Blanks”) is a test assessing your skills in reading comprehension and vocabulary. The difference from the classical multiple-choice test is that instead of choosing one option among four proposed ones, you need to find the word needed to complete the sentence from the passage. This skill helps in understanding collocation of words and cohesiveness of text structure.

Most LUME students often confuse the duolingo english test fill in the blank with vocabulary test. However, this test is a check of a student’s ability to demonstrate cohesion, which means the ability to trace the development of an argument or narration in several sentences.

The test is conducted in the framework of “Interactive Reading” section. You will see a text with missing words, and you will need to select the right word in the drop-down menu. As a rule, the test implies a dual focus on micro-level analysis of the sentence and macro-level comprehension of the passage’s topic.

Format & Structure of Fill in the Blank Questions

Question Layout

Once you see the task, you’ll notice a passage of about 100-150 words. Some words will be omitted in the text and replaced with empty spaces. You need to click on those spaces to get a list of choices for that blank. An Interactive Reading assignment consists of two Fill in the Blanks exercises, which will add a lot to your subscores of Literacy and Comprehension.

Types of Blanks You’ll Encounter

You should recognize three main types of words that can be omitted from the passage. The sooner you recognize their type, the better your chances to complete the task successfully:

Grammar-based blanks: These can consist of a preposition, conjunction, or article, which means you should use your knowledge of English grammar rather than your creative vocabulary to fill in the blank.

Vocabulary-based blanks: Here you are expected to choose the correct noun, verb, or adjective based on its meaning in a particular sentence. Usually, these choices will be similar in meaning, yet only one of them will be appropriate.

Contextual/transitional blanks: These usually consist of transition words such as “however,” “therefore,” “meanwhile,” or “consequently.” Such words establish relationships between two sentences, which makes them hard to complete.

Scoring Criteria

This section is scored using a complex artificial intelligence algorithm provided by Duolingo. While human graders may award partial marks when the answer is “almost correct,” the DET algorithm requires that the word selected must match precisely according to the source text. Your scores will be evaluated based on the following criteria:

• Accuracy: Have you picked the word demanded by the context?
• Efficiency: How much time have you used to fill out this paragraph? Spending too much time filling in a single blank may negatively affect your efficiency score.
• Contextual Coherence: Is the completed text logically coherent?

Why Students Struggle with Fill in the Blank Questions

Most students find the fill in the blank part hard due to their tendency to consider each blank question in isolation. As a result, they tend to make “local mistakes” where a word seems to fit into three words surrounding it but is actually incorrect for the entire context of the paragraph. For example, while a student may select “increase” since it sounds right, the paragraph preceding it has talked about a “downward trend,” hence “decrease” would be the only appropriate selection.

Another challenge in this part of the test is the lack of adequate time. Each student gets only a certain number of minutes to finish the Interactive Reading task, but getting stuck on a challenging blank can make one hurried when attempting other easy blanks. The DET is quite quick; students will feel like running out of time when doing the Interactive Reading task.

Lastly, non-native speakers who cannot identify collocation combinations such as “highly successful” and “mitigate risks” will always end up picking wrong words. Collocation refers to pairs or sets of words used commonly together in a language. Students translating from their native language usually choose natural-sounding words that are “almost correct.”

Proven Strategies to Solve Fill in the Blank Questions

Read the Entire Sentence First

Before marking the answer box, you should first read the whole sentence from beginning to end. In many cases, the clue for filling in the gap lies at the end of the sentence or even in the next sentence. By reading the whole sentence first, you will have a complete idea of what you are looking for in your options. Otherwise, you are just blindly picking an option.

Use Grammar Clues

The words appearing right before and after the blank space should be considered. For instance, the word “an” before the blank indicates that the blank should contain a word starting with a vowel sound. The word “to” appearing right after the blank may suggest a verb such as refer, apply, or lead. In other words, such mechanical clues help you reduce the number of options from five to two.

Focus on Collocations

English is all about collocations. Many fill in the blanks questions from Duolingo English Test may require you to recall common collocations used in English texts. For example, seeing “research” would tell you that the verb preceding it must be either “conducted” or “carried out”. Learning common academic collocations can be quite efficient for this part.

Eliminate Wrong Options

Rather than trying to select the right option only, try to figure out how to eliminate wrong answers. Eliminate those which are the wrong grammatical form (e.g., nouns instead of verbs) and options which are inappropriate within the context. The latter means that informal words like “cool” or “awesome” cannot be the right answers in case of a formal scientific paper.

Manage Time Efficiently

Your target here is to spend 20-30 seconds per gap. Do not waste too much time on a particular question if you do not see an immediate solution. Since this is an adaptive test, you should always maintain your pace, as otherwise, the rest of the test can become quite difficult.

Step-by-Step Approach (With Example)

Here’s a detailed step-by-step approach to dealing with a sentence from the Duolingo English Test fill in the blank section:

Example Sentence: “The committee decided to ________ the proposal because it lacked sufficient funding.”

(A) accept (B) reject (C) ignore (D) discuss

Analysis: Since there is a reason presented in the second part of the sentence (“because it lacked sufficient funding”), there is a cause and effect relation here. We can see that lack of funding is clearly a negative reason about the future of the proposal, meaning that it ends something or prevents it.

Find the Most Suitable Fit: Let’s check all four answers to have a clear look. “Accept” something that lacks funding is highly unlikely to occur, “ignore” something would mean that they never looked at it in the first place; however, they did make a decision about it. While “discuss” could also apply, “reject” the proposal makes more sense than any other option given the circumstances.

Conclusion: “The committee decided to reject the proposal because it lacked sufficient funding.”

Common Mistakes to Avoid

Making It More Complicated than Necessary: Often, the easiest words such as “the” and “and” are right. It does not mean that each blank should be filled with a complex or difficult term. In many cases, high-level English uses very easy functional words.

Over-editing: Trust your initial intuition because it is usually right. You may alter the selection only when you can clearly point out why there was a grammatical error. The more you change your mind, the less confident you appear, and waste your valuable time.

Singular/Plural Mistakes: Pay attention to the noun and ask yourself whether it’s countable or not. We use “fewer” before countable nouns (“apples”), and “less” for non-countable ones (“water”). Those little things are the ones which make the difference.

How to Improve Your Fill in the Blank Skills Fast

The Method of “Active Recall”

Instead of immediately looking up a new vocabulary item that you meet when reading, make an attempt to define it on your own based on its context. It’s exactly what you need for the DET. Afterward, compose three sentences with the use of the new item as a noun, a verb, and an adjective.

Analyzing Transition Words

Compile a list of transitional words and put them into certain categories.

Addition: furthermore, moreover, in addition.

Contrast: however, nonetheless, conversely.

Result: therefore, consequently, as a result.

If you know which category a word belongs to, you’ll instantly see the logic in a gap placed between two sentences.
