I scored 75.
But, I can't understand why the answer for Q.11 is "Evelyn is male".
Not wanting to speculate "Evelyn" is absolutely used by people as female name I chose the answer "Impossible to know from the wording of the sentence whether Evelyn is male or female" due to the reference "other sibling" to Evelyn.
Q.11 “I should like to introduce you to my sister Amanda, who lives in New York, to Mark, my brother who doesn't, and to my only other sibling, Evelyn."
✓Evelyn is male
Evelyn is female
