Meaning: "underground" means below the surface of the ground.

Wrong options:

• undeground: It leaves out the "r". Write "underground". Only the exact spelling gets the mark.

Correct answer: pricing

Explanation: Listen for "its pricing model must". You need a word for the way fares are set, the method of cost.

Meaning: "pricing" means the way prices or fares are decided.

Wrong options:

• prizing: It has "z" where the word has "c". Write "pricing". Only the exact spelling gets the mark.
• prices: "prices" is a close word, but it ends in "es". The speaker says "pricing", which ends in "ing".

Correct answer: expensive

Explanation: On the recording you hear "address the expensive upfront costs". You need a describing word about high cost, it ends in ive.

Meaning: "expensive" means costing a lot of money.

Wrong options:

• expencive: It has "c" where the word has "s". The right spelling is "expensive". Every letter must be correct to get the mark.
• expensively: "expensively" has an extra "ly" at the end. The speaker says "expensive".

Correct answer: subsidies

Explanation: Listen again to "requiring generous subsidies to make fares". You need a money help word in more than one form, so add s.

Meaning: "subsidies" means payments to help cover costs and lower prices.

Wrong options:

• subsudies: It has "u" where the word has "i". Check the letters: "subsidies". A small spelling mistake loses the mark.
• subsidy: "subsidy" is a close word, but it ends in "y". The speaker says "subsidies", which ends in "ies".

Correct answer: average

Explanation: Here you hear "down to an average level". It comes after "an", so you need a word for a thing that means typical or normal.

Meaning: "average" means the normal or typical amount or level.

Wrong options:

• avarage: It has "a" where the word has "e". The right spelling is "average". Every letter must be correct to get the mark.
