Unfortunately the discovery was almost always made on a Sunday according to the excerpt why does Turman planning slaves for late Saturday night or early Sunday morning

Hello. This question is incomplete. The full question is:

Read this excerpt from Harriet Tubman: Conductor on the Underground Railroad.

Unfortunately, the discovery was almost always made on a Sunday. Thus a whole day was lost before the machinery of pursuit could be set in motion. The posters offering rewards for the fugitives could not be printed until Monday. The men who made a living hunting for runaway slaves were out of reach, off in the woods with their dogs and their guns, in pursuit of four-footed game, or they were in camp meetings saying their prayers with their wives and families beside them.

According to the excerpt, why does Tubman plan escapes for late Saturday night or early Sunday morning?

Safe houses on the Underground Railroad operate only on Sundays, when everyone else is working. Such activities as attending church are common on Sundays, so people are less likely to notice they are missing.  Slave trackers do not work on Sundays, so Tubman’s group has more lead time before people start looking for them.  Tubman and her group know exactly where slave trackers are on Sundays, so they know how to avoid them.

Slave trackers do not work on Sundays, so Tubman’s group has more lead time before people start looking for them.

Explanation:

According to the excerpt shown above, we can see that Truman wants to flee between Saturday night and Sunday morning, because the trackers don't work on Sundays. Thus, when someone realized that some slaves had fled, it would be on Monday and that would give the slaves time to be away from the region, thus increasing the chances of a successful escape that would allow them to be free.

yes you could be a life guard if that the question.

from the political point of view it could be said that the candidate   is an effective speaker because she takes a strong position on the issue. it is an open discussion but probably she is making a presentation and can choose which subjects she wants to address. she is very likely to attain her aim which is to convince voters to accept her proposal.
