Gateway B1 Unit 6 Test Standard Reading

Questions: 15 | Attempts: 4306 | Last updated: Mar 22, 2025

Sample Question
A few years ago everyone was talking about the new electric cars. These cars were cleaner and quieter andthey were going to be the answer to our pollution problems. (1) ……………………… Why aren’t our roads full ofelectric cars? Why are we still sending out huge amounts of pollution into the atmosphere and using oil fasterthan the oil companies can produce it?

And it isn’t because of the price.

The main problem is the cost, but they are already cheaper than all electric cars.

So, where are they?

People worry about not having enough electricity to get to their destination.

People need a car that is reliable.

It’s not because the cars aren’t for sale.
