IELTS Reading T/F/NG: Why You Keep Mistaking "NG" for "False" – Grapple with Subjects, Scope, and Comparisons

IELTS Reading True/False/Not Given questions are really good at playing tricks.

When you look at the question, you often get a feeling like, "Hey, this statement seems off," and before you know it, you’ve quickly clicked False. But when you check the answer key, it turns out to be Not Given. After getting it wrong several times in a row, many people start to doubt whether they even understood the passage. However, I later discovered that many times it’s not a failure of reading comprehension—it’s just judging too hastily. Especially when you see familiar words, your brain automatically biases the rest, often leading you to conclude that the original statement is the opposite, when it isn't.

Many prep articles online warn you about roughly the same thing: you need clear evidence to prove False, while Not Given simply means the information is insufficient, not that you don't think it fits. The logic isn't complicated. But the moment you walk into the exam hall, you somehow forget this small boundary.

Judgment Goes Incorrect When Subjects Aren't Aligned

I personally think the sneakiest trick in True/False/Not Given questions isn't unfamiliar words; it's the "stealing of the subject."

The original text says some teenagers, but the question changes it to students. The original text says the research team, but the question changes it to most scientists. If your eyes only catch the core nouns, your brain automatically assumes they are "about the same thing." But they really aren't. A change in the subject often changes the scope along with it.

So, after locating the sentence, don't rush to select an answer. Stop for half a second and look closely. Exactly who is performing the action? Who is expressing the conclusion? If the subject doesn't align, the question is already in danger. Many Not Given scenarios aren't that the text didn't mention anything at all; rather, the text mentions related people or events but never mentions the specific subject mentioned in the question.

Scope Words Widely Open the Gap Between Similar Sentences

Another annoying thing in these questions is scope words.

Look at words like all, some, only, mainly, often, rarely. Despite their harmless appearance, they can be very deceptive. If the original text says, "Some students prefer offline classes," and the question writes, "All students prefer offline classes," you cannot assume they are the same just because the second part sounds similar. That initial "leak" significantly widens the scope.

I’ve seen many people trying to figure out questions who obsessively grab concrete nouns and striking numbers, but they miss these small scope words. Then they get it wrong and feel aggrieved, thinking the question and the original text clearly said the same thing. But they didn't. In IELTS Reading, situations where "small words lead to big twists" are common. The more you think a word is insignificant, the more likely you are to trip over it.

Comparison Relationships Are the Real Ambush Spot

There's another trap that often appears in the comparative degrees and chronological order.

The original text says more effective than, but the question swaps it for as effective as. The original text says a method appeared earlier, while the question writes it as later. If you only stare at the same method name or the same phenomenon name, you easily overlook the true deciding factor: the word next to it.

The most annoying thing about these questions is that they give you a sense of "comfort" knowing you've "found the original text." But what you've found is often just the location, not the answer. If the comparison relationship doesn't match, if the chronological order is wrong, or if the degree isn't aligned, it’s still wrong.

"Not Given" Feels More Like Incomplete Information Than Missed Sentences

Many people think Not Given means "I couldn't find the original sentence," which is a mindset that easily leads you astray.

The reality is more like this: you found roughly the right location and saw roughly the right topic, but the specific snippet of information the question asks for is simply missing from the original text. It doesn't explicitly support the statement, nor does it explicitly contradict it. So, don't force a judgment.

For instance, if the question says a policy "is cheaper for most families," but the original text only says "helps a part of families reduce transport costs." You cannot "brain-add" the conclusion and think, "It should overall be cheaper." No. The original text never completed the thought that the piece regarding most or the judgment of "overall cheaper savings" was made. Incomplete information is just that—incomplete.

The Secondary Verification Move Catches Many Impulsive Errors

Now, when doing these types of questions, I force myself to perform a simple动作 after scanning: compare the question and original text on three points.

1. Is the subject the same group of people?
2. Has the scope widened or shrunk?
3. Have comparison relationships been secretly altered?

If any of these three points is still blurry, I generally won't immediately press False. Many errors happen because I was too eager to try and "prove it's wrong." But True/False/Not Given isn't a debate competition; you don't need to win immediately. You must first confirm that the original text explicitly contradicts the statement before you can judge it False.

Analysis Needs to Be "Down-to-Earth" to Be Truly Remembered

When reviewing these types of questions, I don't suggest just writing "judgment error" on your paper—that's about as useful as writing nothing at all.

You should try to write things down in a way that feels more colloquial, even if it sounds a bit unprofessional. For example:

• I mistook some for all again.
• I clicked without thinking after seeing a similar word.
• I filled in the gap with my own assumption for a part of the people in the original text.
• I didn't notice the object of the comparison after than.

Although these records aren't "high-level" logic, they actually trigger a small mental alarm for you the next time you see that specific trap. Many people aren't necessarily bad at specific types of questions, but they keep tripping over the same step simply because they haven't explicitly identified that step before.

A Steady Practice Path Is More Useful Than Esoteric Analysis

If you've been grinding through reading passages recently, I strongly suggest you practice these questions in a "dumber" and "slower" way. Don't chase a high volume first; chase consistency in your process for every single question.

First check the subject, then look at the scope, then check the comparison relationships, and finally decide if it is True, False, or Not Given. This process might be a bit tedious and annoying at first, but once you're comfortable with it, your mindset will be much more stable.

If you often find your practice, error logging, and review of old questions scattered across different places, you can also try YouShow IELTS. You can download it from the Apple App Store or visit the official website at https://ielts.youshowedu.com/en. Although the app was originally named YouShow PTE, it is quite handy for recording IELTS Reading error causes and review points—at least you won't forget that you're constantly missing scope words one day only to forget about it the next.

Your Score Will Stabilize Once You Clarify the Boundaries

Ultimately, True/False/Not Given questions aren't playing psychological games with you; they just love hiding boundaries in small places. Whether the subject has changed, if the scope has drifted, if the comparison relationship has twisted, and whether the original text is unfinished or explicitly contradictory—all these details matter.

Don't keep thinking that mistaking Not Given for False means your reading comprehension is poor. Sometimes you’re just too impatient, too eager to pick an answer quickly. Take a half-second pause, clearly identify those small details, and then strike. This action might look clumsy, but it is often far more useful than memorizing a bunch of stiff tricks.
