1............... he wasn't schooled, his common sense guided him through life.
Wrong!
Use "Though" to introduce a contrast between not being schooled and having common sense.

Wrong!
Use "Ever since" to mean from that time until now with the present perfect.
4The tenants complained that there ............... not enough hot water.
Wrong!
In reported speech after a past reporting verb, "was" matches the singular subject and past time frame.
5The boy remained in concealment ............... the bully went away.
Wrong!

Wrong!
The fixed expression is "conferred on" when an honor or diploma is formally given to someone.

The singular subject "a pregnant woman" needs "does" before the base verb in a negative present simple clause.

The verb "leaves" is parallel with "arrives" for a general habit in the present simple.
