Pick the word (or words) that fill the gap best.At a very hard time during World War 2, the British leader Winston Churchill made a famous speech to Parliament, aiming to raise our courage. His last words were: 'Let us (...) brace ourselves to our duties, and (...) men will still say, ' ... ... was their finest hour'.'.

These and those are demonstrative words.

Often we need to distinguish one item among several: 'This hat', 'those gloves'.
