Question

Complete the sentence with a suitable option:

Sunlight filtering ________ the stained glass window created a mosaic of colours on the floor.

• A. into
• B. through
• C. at
• D. by

Answer 1

Answer: (B)

through

The word, 'filtered' is a verb which means 'passed through something, usually in order to remove unwanted material'. It is mostly used with the preposition, 'through', sometimes with the preposition 'into' and 'to' as well. The choice of preposition depends upon the word (or words) which follows the preposition.

The phrase, 'filtering into the stained glass window' is incorrect as the sunlight is not filtering into and reaching the stained glass window. The stained glass window is not the destination, but the medium. Hence, option A is incorrect.

As the sunlight passes through the medium i.e. the stained glass window, the appropriate preposition is 'through', as given in option B.

Option C and D are incorrect as the words, 'filtering at' and "filtering by" are grammatically incorrect usages.
