Passage Reference: In order to reduce energy' costs, the design allowed for natural lighting in as many public areas as possible, supplemented by solar-powered units.

Common Mistake: Some students choose solar-powered units because they also relate to energy. But solar-powered units are extra support, not the main feature in public areas. This is a context shift trap.

Paraphrasing: Passage: 'natural lighting in as many public areas as possible' = Diagram: 'energy-saving feature in public areas'

Tips: When two options are both about energy, check which one the sentence focuses on first.

Key Vocabulary:

• supplemented = added to
• public areas = shared spaces

Question Focus: The diagram shows a comparison between two ventilation systems and asks which one was avoided.

Correct Answer: C

Passage Reference: Wherever possible, passive ventilation was used instead of mechanical air- conditioning.

Why this is correct: The diagram is asking which system was not preferred. The passage says passive ventilation was used instead of mechanical air- conditioning, so the avoided system is mechanical air- conditioning.

Common Mistake: Students sometimes choose natural lighting because it sounds environmentally friendly. But this sentence is about ventilation, not lighting. This is a wrong section trap.

Paraphrasing: Passage: 'instead of mechanical air- conditioning' = Diagram: 'system not used'

Tips: Watch for phrases like 'instead of' because they signal contrast and help you choose the correct label.

Key Vocabulary:

• passive = using natural processes
• ventilation = movement of air

Question Focus: The diagram shows water collection and asks what type of water was collected.

Correct Answer: F

Passage Reference: Stormwater run-off was collected for toilet flushing.

Why this is correct: The diagram label refers to collected water. The passage clearly states that storm water run-off was collected, so the answer is storm water.

Common Mistake: Some students pick rainwater because it is mentioned earlier. But rainwater is used for pitch irrigation, not this part. This is a context shift trap.

Paraphrasing: Passage: 'Stormwater run-off was collected' = Diagram: 'type of collected water'

Tips: If water is mentioned more than once, match each use carefully to the correct purpose.

Key Vocabulary:

• run-off = water that flows away
• stormwater = rain after storms

Question Focus: The diagram shows what the collected water was used for.

Correct Answer: D

Passage Reference: Stormwater run-off was collected for toilet flushing.

Why this is correct: The diagram asks about the purpose of the collected water. The passage directly says it was used for toilet flushing, so the answer is flushing.

Common Mistake: Students sometimes choose pitch irrigation because it is another water use. But that use is for rainwater from the roof, not stormwater. This is a partial truth trap.

Paraphrasing: Passage: 'for toilet flushing' = Diagram: 'used for ___'

Tips: Always link the water source and the water use together before choosing an answer.

Key Vocabulary:

• flushing = cleaning toilets with water
• irrigation = watering land

Question Focus: The diagram shows where roof water was directed and asks its final use.

Correct Answer: G

Passage Reference: Rainwater collected from the roof ran off into storage- ranks, where it could be tapped for pitch irrigation.

Why this is correct: The diagram refers to rainwater from the roof. The passage explains it was stored and then used for pitch irrigation, so that is the correct answer.

Common Mistake: Some students choose flushing because it also involves water. But flushing uses stormwater, not roof rainwater. This is a wrong section trap.

Paraphrasing: Passage: 'rainwater ... for pitch irrigation' = Diagram: 'roof water used for ___'

Tips: Follow the process step by step. Roof water and stormwater are treated differently.

Key Vocabulary:

• pitch = sports field
• irrigation = watering

General Tips:

• Diagram questions usually follow the same order as the passage. Read from top to bottom.
• Look for exact nouns in the passage that match the diagram labels.
• If similar options appear, check the water source, energy source, or system carefully.
• Cross out each option after you use it so you do not reuse it by mistake.
