In "the red-headed league," why does sherlock holmes beat upon the pavement outside of jabez wilson's office?

a.
he wants to find out if the ground under the pavement has been dug out.

b.
he wants to find out where john clay is hiding in saxe-coburg square.

c.
he wants to find out whether wilson can hear him inside the office.

d.
he wants to find out how strong his walking stick is in case he needs to protect himself.

i am thinking its a, but i really dont know, a or b.

The correct answer is:  A.  He wants to find out if the ground under the pavement has been out.   Sherlock Holmes hitting the pavement with his vault was looking for a hollow place, according to the sound emitted by the blow, maybe he is looking for a basement.

i’m   sure probably just geuss and see which one you can get right, i’m pretty sure it is the combination of goods and services

the arab empire adopted the muslim religion as their main belief. arabs would influence the people from the territories they invaded towards islam (the muslim belief).

nevertheless, throughout the history of the arab empire, rulers brought intellectual individuals from other religions to their centers of learning. these other foreigners included jews, christians, greeks, persians, and indians.   these resulted in the adoption of important knowledge developed by these cultures by the arabic empire. for example, the works of aristotle were translated from greek to arab and indian scientists brought the numerical concept of "zero" to the arabs.

nowadays, 93% of the arab population is muslim, which at the same time is subdivided in sects including the sunni, zaini, alawi, shia. the remaining 7% is composed mainly of christians.
