• D. Lines 48–55 ("The recent . . . 1964")

Correct Answer: B

Explanation:

(B) See the explanation to question 44. Lines 13–23 reference the shift from static to expanding universe based on discoveries by Einstein and Hubble. In the first paragraph, the passage deals with the 19th century. "After the turn of the next century" must then refer to the beginning of the 20th century.
