The words which do not change their degree in the degree of comparison
Answers
ANSWER
When the sentence of the superlative degree is changed to the positive degree of comparison, without changing the meaning of the sentence, a negative word 'no' is added. The structure of the positive sentence that has been transformed from a superlative one, starts with the negative phrase 'No other' and contains the phrase of the positive "as old as". The noun 'city' is of the highest degree in terms of age 'oldest', compared to the rest of the cities in that country. Option A is correct because "as old as" is in the positive degree, and by adding the phrase "no other" the sentence has not changed in its meaning. Option B is incorrect as the phrase "older than" is of the comparative degree, and the structure of the sentence is not of the positive degree. Also, the meaning of the sentence has changed. Option C is incorrect because it's in the comparative degree and also its meaning has changed. Option D is incorrect because it's of the superlative degree and the meaning is completely opposite from the original sentence.
