Directions: For the following question, choose the option that fills up the blank most correctly.

Reading the greatest literary artists among historians will help, but do not forget that what was acceptable style in 1850 might seem ________ today.

'Don't forget' in the sentence emphasizes on the negative aspect of the blank. This implies that the literary style that was acceptable in 1850 might be not so important today. Thus, 'experienced' in (1) and 'developed' in (4) are ruled out. 'Turgid' means using or characterized by high-sounding but unimportant or meaningless language, which fits our prediction. Hence, (2) is the answer.
