Each of the questions consists of a certain number of sentences. Some sentences are grammatically incorrect or inappropriate. Select the option that indicates the grammatically correct and appropriate sentence(s).
Explanation:
Statements B and C are incorrect. Statement B should read ‘Ever since the Enlightenment…’ (the Enlightenment: a philosophical movement of the 18th century, characterized by belief in the power of human reason and by innovations in political, religious, and educational doctrine). Statement C should read "…. in the 1820s". From the above interpretation, options 2, 3 and 4 are eliminated. Hence, the correct answer is option 1.
