Given the task definition and input, reply with output. You need to read the given passage and construct a question about the information present in the passage. The question should be answerable from the passage. Most importantly, only those questions are allowed whose answers cannot be determined from a single sentence. Do not generate questions that require only a single sentence to answer. Instead, try to combine two sentences and create a question from that combination. Do not create open-ended questions, i.e., the answers to them cannot be found precisely from the information provided in the passage.

Paragraph- Sent 1: Soon Sweetwater realised that his work was over for the night and planned to leave.
Sent 2: But there was one point to be settled first.
Sent 3: Was there any other means of exit from these grounds save that offered by the ordinary driveway?
Sent 4: He had an impression that in one of his strolls about, he had detected the outlines of a door in what looked like a high brick wall in the extreme rear.
Sent 5: If so, it were well worth his while to know where that door led.
Sent 6: Working his way along in the shadow cast by the house and afterward by the stable itself, he came upon what was certainly a wall and a wall with a door in it.
Sent 7: He could see the latter plainly from where he halted in the thick of the shadows.
Sent 8: The moonlight shone broadly on it, and he could detect the very shape and size of its lock.
Sent 9: It might be as well to try that lock, but he would have to cross a very wide strip of moonlight in order to do so, and he feared to attract attention to his extreme inquisitiveness.
Sent 10: Yet who was there to notice him at this hour?
Sent 11: Mr. Cumberland had not moved, the girls were upstairs, Zadok was busy with his paper, and the footman dozing over his pipe in his room over the stable.
Sent 12: Sweetwater had just come from that room, and he knew.

Does Sweetwater find out where the door leads?
