Interpreting Information
Recognising This Question Type
Interpreting Information (II) gives you a dense passage, chart, or table and 5 statements to mark Yes or No. Like Syllogisms, these use the drag-and-drop format and are worth 2 marks.
The stimuli are typically scientific, medical, or statistical - longer and more detailed than Syllogism premises. This question type feels the most like Verbal Reasoning, but the standard of evidence is different.
These make up ~5-6 questions (~14.3% of DM). Target time: 60-90 seconds per set.
How II Differs from Verbal Reasoning
This is a distinction you need to get right, because it changes the standard of evidence for every statement.
| Verbal Reasoning | Interpreting Information | |
|---|---|---|
| What's allowed | Only what the passage explicitly states | Reasonable inference is allowed |
| Example | "Drought" from "no rain for 6 months" → Can't Tell | "Drought" from "climatic fluctuation" → Yes (drought is a form of climatic fluctuation) |
| Standard | Match only - no inference beyond text | Must follow - one-step logical deduction OK |
The golden rule: If the statement must be true given the information, it's Yes. If it could go either way - even slightly - it's No. You've got more room for inference than VR, but "could be true" still isn't enough.
The Technique: Claim-Check
Step 1: Skim the stimulus (10-15s). Read the first sentence for the topic. Scan the rest, noting what each sentence or data point covers. Don't memorise - just build a mental map. "S1 = definition. S2 = historical problem. S3 = new technology. S4 = statistics."
Step 2: Read the statement. What does it CLAIM? Break it down: what topic does it address? What specific claim does it make? Does it use absolute language ("all", "none", "always") or qualified language ("some", "can")?
Step 3: Find the matching content. Use non-interchangeable keywords - proper nouns, technical terms, numbers, percentages - to locate the relevant sentence(s). These can't be swapped for synonyms, so they're reliable anchors.
Step 4: Compare claim to source. Does the passage support EXACTLY what the statement says? Check for: exaggeration (qualified to absolute), unsupported comparison, going beyond, contradiction.
Step 5: Verdict. Must be true - Yes. Could go either way, contradicts, or goes beyond - No.
The Yes/No Decision Guide
| What the passage does | Verdict |
|---|---|
| Directly supports the statement (same claim, possibly inferred one step) | Yes |
| Says the opposite (contradicts the statement) | No |
| Says nothing about this topic (statement goes beyond the passage) | No |
| Supports part of the statement but doesn't address another part | No |
| Statement exaggerates the passage ("reduce by up to 50%" → "painless") | No |
Unlike VR, there's no "Can't Tell" option. If the passage doesn't support it, it's No - whether the passage contradicts it or simply doesn't address it.
Worked Example 1: Text Passage
Passage:
"Type 1 diabetes is an auto-immune condition that cannot be prevented and accounts for about 8% of all diabetes cases. Historically, the sufferers were condemned to countless blood sugar tests and worry about an attack brought on by dangerously low blood sugar while they slept. However, the latest wearable tech now provides real-time continuous glucose monitoring for adults and children and it can reduce the need for often painful finger-prick testing by up to 50%."
First, build your mental map: S1 = definition + stats. S2 = historical problem (blood sugar tests, nighttime danger). S3 = new tech solution + stats.
| Statement | Claim being made | Where to look | Reasoning | Answer |
|---|---|---|---|---|
| (a) "Type 1 diabetes is caused by the body's own immune system." | Cause = body's own immune system | S1: "auto-immune condition" | Auto-immune means the body's immune system attacks itself. One-step inference from a technical term. Must follow. | Yes |
| (b) "Controlled diet and regular checks can impede the onset of type 1 diabetes." | Diet + checks can prevent/slow it | S1: "cannot be prevented" | "Impede the onset" = prevent/slow. Directly contradicts "cannot be prevented." | No |
| (c) "Low glucose levels can be dangerous, especially at night time." | Low glucose = dangerous + worse at night | S2: "dangerously low blood sugar while they slept" | Sleeping = nighttime (reasonable inference). "Dangerously" = dangerous. Must follow. | Yes |
| (d) "Use of wearable glucose monitors means the management of diabetes is painless." | Management is painless | S3: "reduce the need for often painful finger-prick testing by up to 50%" | "Up to 50%" reduction isn't elimination. Some painful testing remains. "Painless" exaggerates. | No |
| (e) "Children benefit from the new technology more than adults." | Children benefit MORE than adults | S3: "for adults and children" | Lists both groups but never compares their relative benefit. The statement introduces a comparison the passage doesn't make. | No |
Time check: The passage is 3 sentences. Mapping it takes ~10 seconds. Each statement takes ~10-15 seconds once you know where to look. Total: ~70 seconds.
Worked Example 2: Table/Data Interpretation
Stimulus: A table showing patient outcomes across three hospitals.
| Hospital | Admitted | Survived | Deaths |
|---|---|---|---|
| City North | 420 | 378 | 42 |
| Riverside | 310 | 283 | 27 |
| St. Mary's | 550 | 462 | 88 |
| Statement | What the claim is | Check against data | Answer |
|---|---|---|---|
| (a) "City North had the highest survival rate." | City North's rate was the best | City North: 378/420 = 90%. Riverside: 283/310 = 91.3%. St. Mary's: 462/550 = 84%. Riverside is higher. | No |
| (b) "St. Mary's treated the most patients." | St. Mary's had the highest admissions | 550 > 420 > 310. Yes. | Yes |
| (c) "Riverside had fewer deaths because it had fewer patients." | Fewer deaths BECAUSE of fewer patients | The table shows Riverside had fewer deaths (27) and fewer patients (310), but "because" implies a causal link. The data shows correlation, not cause. Riverside also had the best survival rate (91.3%), so it wasn't just about volume. | No |
| (d) "More than 85% of all patients across the three hospitals survived." | Combined survival rate > 85% | Total survived: 378 + 283 + 462 = 1123. Total admitted: 420 + 310 + 550 = 1280. 1123/1280 = 87.7%. Yes, more than 85%. | Yes |
Time check: Quick arithmetic for each row. The tricky one is (c) - it smuggles in a causal claim that the data can't support. ~60 seconds total.
The 4 Common Traps
Trap 1: Exaggeration
The passage says something qualified. The statement removes the qualification.
| Passage says | Statement says | Answer |
|---|---|---|
| "can reduce" | "will eliminate" | No |
| "up to 50%" | "by half" | No ("up to" ≠ exactly) |
| "for adults and children" | "more for children" | No (no comparison made) |
| "accounts for 8%" | "a rare condition" | Yes (8% is small) |
| "cannot be prevented" | "diet cannot impede it" | Yes (cannot prevent = cannot impede) |
Trap 2: Correlation vs. Causation
The passage shows two things happening together. The statement says one causes the other. Unless the passage explicitly states causation, the causal claim doesn't follow.
Passage: "Countries with higher tea consumption have lower rates of heart disease."
Statement: "Tea consumption prevents heart disease."
Answer: No. The passage shows correlation, not causation. Other factors (diet, healthcare access) could explain it.
This is one of the most reliable traps in II. Any time a statement uses "because," "leads to," "causes," or "results in," check whether the passage actually establishes that causal link or just describes a pattern.
Trap 3: Misreading Scales and Axes
When the stimulus is a chart or graph:
- Check what the y-axis measures (absolute numbers? percentages? rates per 1000?)
- Check the scale intervals (is the gap between gridlines 10 or 100?)
- Check whether the x-axis is evenly spaced (time series with missing years can mislead)
A statement might say "doubled between 2010 and 2020" when the chart shows it went from 40 to 60 - visually looks like a big jump if the y-axis starts at 30, but it's a 50% increase, not 100%.
Trap 4: True But Doesn't Answer the Question
A statement can be factually correct based on the passage but not what the question is asking. This is rare in II but it happens: the statement matches the passage topic but answers a different question than the one posed.
Handling Numerical Inference
II passages often embed numbers you need to calculate with:
Passage: "…the complete egg weighs about 58g, of which 18g is the yolk."
Statement: "The layers other than the yolk weigh about 2.23 times more than the yolk."
Calculation:58 − 18 = 40g(non-yolk).40 / 18 = 2.22…
"About 2.23 times" → Yes (close enough).
Rule: "About" or "approximately" gives you rounding room. If your calculation is within a few percent of the statement's claim, it follows.
Underlying Skills
II questions test three skills from the DM taxonomy:
- D1: Scientific / Technical Passage Inference - close reading of dense text, distinguishing what's stated from what's merely implied. The key is not importing unstated conclusions.
- D2: Numerical / Quantitative Passage Inference - extracting numbers from text and performing calculations to verify claims. The trap is arithmetic errors or mixing up percentages and ratios.
- D3: Graphical / Chart Data Interpretation - reading and interpreting visual data. Check axes, scales, and units before drawing conclusions.
The Claim-Check technique applies to all three. The difference is where you find the matching content: in text (D1), in embedded numbers (D2), or in charts/tables (D3).
When to Flag and Skip
II passages vary enormously in difficulty. Some are 3 clear sentences about a medical topic. Others are dense paragraphs about obscure scientific studies.
| First-line read | Decision |
|---|---|
| Topic clear, passage short | Attempt immediately (60-90s) |
| Topic clear but passage very long | Attempt - but scan, don't read word-by-word |
| Topic opaque, language dense | Flag. Guess your best for each statement, return if time allows |
The II Checklist (per statement)
Run through this every time:
- What does the statement claim?
- Where in the passage/data is this topic covered?
- Does the passage support the claim exactly, or does the statement go further?
- Does the statement add a causal link the passage doesn't make?
- Does the statement strengthen, weaken, or match the passage's language?
If you can answer "the passage says this, and the statement says the same thing or a valid one-step inference" - it's Yes. Anything else is No.
Common Mistakes
- Applying VR logic - In VR, "drought" from "climatic fluctuation" would be Can't Tell. In DM, a reasonable one-step inference is valid. Adjust your threshold.
- Accepting "could be true" - "Could be true" isn't "must be true." If there's any reasonable scenario where the statement is false given the passage, it's No.
- Missing the exaggeration - "Up to 50% reduction" isn't the same as "50% reduction." "Can improve" isn't "will improve." Watch for strengthened language.
- Assuming causation from correlation - The passage says two things co-occur. The statement says one causes the other. That's a leap the data doesn't support.
- Reading the whole passage before looking at statements - This wastes time. Build your map first, then check each statement against the relevant section.
Summary
| Element | Detail |
|---|---|
| Technique | Claim-Check: skim stimulus, read statement, identify its claim, find matching content, compare |
| Time target | 60-90 seconds per set (5 statements) |
| Yes | Statement must be true given the passage (one-step inference allowed) |
| No | Statement contradicts, exaggerates, or goes beyond the passage |
| Key difference from VR | More inference permitted - "auto-immune" = "body's own immune system" is valid |
| Key traps | Exaggeration, correlation-causation confusion, misreading chart scales, unsupported comparisons |
