Quiz playing is a wonderful way to increase your knowledge of English as a Second Language. Remember that all of our ESL quizzes have titles that are both friendly and technical at the same time… In the case of this quiz you might like to tell your friends about “How Likely?” but no doubt your teachers will talk about the “Modals quiz”! If you hear a technical term and you want to find a quiz about the subject then just look through the list of quiz titles until you find what you need.
This quiz on modals tests you on the scale of likelihood of something happening.
How likely are you to pick up the 'signals' in English, about whether something is really true or will actually happen? (Sometimes a person may say or write something that may seem to give you hope, but may not be meant to say quite what appears!)
This quiz will help you to distinguish some more of the subtle differences and test you on modals.
Answer 1 simply refuses to accept any possibility of a fault: '100% of brand-new machines should do their job without problem.'
Answer 2 suggests there are no circumstances or means in which a fault could have arisen, if the machine was checked at the factory and has been installed and started in accordance with the instructions.
Answer 3 appears to suggest that nobody gave the machine permission to malfunction. This isn't what we would normally say.
Answer 4 expresses the idea that the machine has 'failed in its duty' and 'not done what it was supposed to'; in an ideal world, such things ought never to happen!
