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 “These and Those” but no doubt your teachers will talk about the “Demonstrative Words”! 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.
ESL often appears to be full of difficult technical terms as in this case – demonstrative words – and this can be very confusing for beginners. It might help to know these terms if you have already studied your own language in great depth but for most of us it is only necessary to know how words are used, not what they are called!
You can't really have 'this ... and this' in the same sentence (though sometimes it does make sense).
'These' and 'those' refer to plural things, and one other car can't very well be plural.
