Meaning: "technology" means tools and systems used to solve problems.

Wrong options:

• techonology: It adds an extra "o". The right spelling is "technology". Every letter must be correct to get the mark.
• technologies: "technologies" is a close word, but it ends in "ies". The speaker says "technology", which ends in "y".

Correct answer: network

Explanation: You hear "in an integrated network". It comes after "an", so only one is needed.

Meaning: "network" means a connected system of devices or services.

Wrong options:

• netwerk: It has "e" where the word has "o". Write "network". Only the exact spelling gets the mark.
• networks: "networks" has an extra "s" at the end. The speaker says "network", with no "s".

Correct answer: efficiency

Explanation: Listen for "enhances efficiency but also". The idea shows how well things work.

Meaning: "efficiency" means doing tasks with less waste or time.

Wrong options:

• effeciency: It has "e" where the word has "i". Write "efficiency". Only the exact spelling gets the mark.
• efficient: "efficient" is a close word, but it ends in "t". The speaker says "efficiency", which ends in "cy".

Correct answer: sustainability

Explanation: On the recording you hear "promotes environmental sustainability". It follows "environmental", so you need the idea or state.

Meaning: "sustainability" means caring for the environment for the future.

Wrong options:

• sustanability: It leaves out the "i". The right spelling is "sustainability". Every letter must be correct to get the mark.
• sustainable: "sustainable" is a close word, but it ends in "le". The speaker says "sustainability", which ends in "ility".

Correct answer: significant

Explanation: Listen again to "become increasingly significant, offering". This is a describing word, not the how word.

Meaning: "significant" means important or having a big effect.

Wrong options:

• signficant: It leaves out the "i". Write "significant". Only the exact spelling gets the mark.
• significantly: "significantly" has an extra "ly" at the end. The speaker says "significant".

Correct answer: challenges

Explanation: Here you hear "address urban challenges". More than one is needed, so add s at the end.

Meaning: "challenges" means problems or things that need solutions.

Wrong options:

• chalenges: It leaves out the "l". Check the letters: "challenges". A small spelling mistake loses the mark.
• challenge: "challenge" has no "s" at the end. The speaker says "challenges", so write the "s".
