A.I. Explanation:

Question Focus: Detail question - identifying stated uses of groundwater

Correct Answer: A

Passage Reference: At present, however, experts believe excessive amounts of ground water are being squandered on aesthetic projects such as keeping parks, gardens and golf courses green.

Why this is correct: This is correct because the passage clearly says groundwater is used for keeping parks, gardens and golf courses green, which are recreational areas.

Paraphrasing: Passage: 'keeping parks, gardens and golf courses green' = Option: 'maintaining recreational areas'

Tips: Look for examples in the passage. Lists of examples often hide correct answers.

Key Vocabulary:

• aesthetic = related to appearance

Question Focus: Detail question - checking if a use is mentioned

Correct Answer: B

Passage Reference: Aside from more judicious use of groundwater, many experts also believe that we need to look at harnessing other potential sources in order to meet our water needs. During rainy seasons, for example, urban areas are inundated with storm water and flash flooding that can bring cities to a standstill. Better storm water control mechanisms could potentially capture and preserve this rainwater for use at a later date.

Why this is correct: This is wrong because the passage never mentions sewer systems or wastewater management. Students may imagine this use from real life, but it is not stated. This is a Not Given trap.

Tips: Do not choose options based on real-world knowledge. Choose only what the passage says.

Question Focus: Detail question - checking for irrelevant ideas

Correct Answer: C

Passage Reference: Groundwater is renewable through surface run off (and, at a much slower rate, in organic springs where it is literally drip fed through rock on its way to the aquifers).

Why this is correct: This is wrong because underground sports are never discussed. The word underground might tempt you, but the passage talks about water movement, not sports. This is a Context shift trap.

Tips: Be careful with options that borrow one word from the passage but change the topic.

Question Focus: Detail question - environmental use of groundwater

Correct Answer: D

Passage Reference: But the proposed scheme is riddled with difficulties: low flow rates are hampering extraction; replenishment rates are lower than expected; and salinity imbalances caused by the procedure could wreak havoc on efforts to preserve wetland flora and fauna ecosystems that rely on a plentiful, clean and steady supply of water from the aquifers.

Why this is correct: This is correct because the passage explains that aquifers provide a clean and steady supply of water needed to preserve wetland flora and fauna ecosystems, which means supporting wildlife habitats.

Paraphrasing: Passage: 'preserve wetland flora and fauna ecosystems' = Option: 'supporting wildlife habitats'

Tips: Environmental effects often appear as uses, even if they are indirect.

Key Vocabulary:

• flora and fauna = plants and animals

Question Focus: Detail question - confusing groundwater with storm water

Correct Answer: E

Passage Reference: During rainy seasons, for example, urban areas are inundated with storm water and flash flooding that can bring cities to a standstill. Better storm water control mechanisms could potentially capture and preserve this rainwater for use at a later date.

Why this is correct: This is wrong because the passage talks about storm water, not groundwater, being captured in cities. Mixing these two ideas is a Context shift trap.

Tips: Check you are answering about the correct type of water mentioned in the question.

Key Vocabulary:

• storm water = rainwater from heavy rain

Question Focus: Detail question - domestic use of groundwater

Correct Answer: F

Passage Reference: Bore water for any domestic purposes has since been off limits due to chemical seepage from an estimated eight industrial sites.

Why this is correct: This is correct because the passage directly mentions domestic purposes, even though it says this use was later restricted.

Paraphrasing: Passage: 'domestic purposes' = Option: 'personal household use'

Tips: Even if a use is stopped or criticised, it still counts as a mentioned use.

Key Vocabulary:

• domestic = related to the home

Question Focus: Detail question - misreading technical description

Correct Answer: G

Passage Reference: Groundwater is renewable through surface run off (and, at a much slower rate, in organic springs where it is literally drip fed through rock on its way to the aquifers).

Why this is correct: This is wrong because the passage mentions organic springs, but says nothing about hot springs or bathing. Adding extra details makes this a Partial truth trap.

Tips: If an option adds extra details not in the passage, it is usually wrong.

Key Vocabulary:

• spring = natural source of water

Question Focus: Detail question - agricultural or animal use

Correct Answer: H

Passage Reference: A strategy group known as the Great Artesian Basin Consultative Council has also published a management plan that involves capping some bores (to prevent further declines in pressure) and rehabilitating hundreds of other bores and bore drains with troughs and polyester piping (to prevent water seeping into the earth).

Why this is correct: This is correct because troughs are used to give water to animals, so the passage shows groundwater is used for providing water for animals.

Paraphrasing: Passage: 'troughs' = Option: 'providing water for animals'

Tips: Sometimes the use is implied by an object mentioned, like troughs for animals.

Key Vocabulary:

• trough = long container animals drink from

General Tips:

• For multiple-answer MCQs, check every option carefully. There can be several correct answers.
• These questions follow passage order. Use earlier answers to help locate later ones.
• Underline exact uses mentioned in the passage, then match options to those lines.
• Avoid using real-world knowledge. IELTS only tests what is written in the text.
