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: There were others far more perturbed by that odd conjunction of diners than the puzzled host, who merely expected Mrs. Bates to belabor him with a rolling pin.
Sent 2: Mr. Siddle, for instance, had just closed his shop when the five met.
Sent 3: That is to say, the dark blue blind was drawn, but the door was ajar.
Sent 4: He came to the threshold, and watched the party until the bridge was neared, when one of them, looking back, might have seen him, so he stepped discreetly inside.
Sent 5: Being a non-interfering, self-contained man, he seemed to be rather irresolute.
Sent 6: But that condition passed quickly.
Sent 7: Leaning over the counter, he secured a hat and a pair of field-glasses, and went out.
Sent 8: He, too, knew of Mrs. Jefferson's weakness for shopping in Knoleworth, and that good lady had gone there again.
Sent 9: Her train was due in ten minutes.
Sent 10: A wicket gate led to a narrow passage communicating with the back door of her residence.
Sent 11: He entered boldly, reached the garden, and hurried to the angle on the edge of the cliff next to the Martins' strip of ground.
How many people are in the party Mr. Siddle watched near the bridge?
