darth reid, eigrp summarization

I need some help interpreting Section V.5 of Solie's Darth Reid Lab.

"Summarize EIGRP so that the lab network has only one route for both
160.100.1.0 and 161.100.1.0."

The solution has two ip summary-address statements, one for 160.100.1.0/24
and one for 161.100.1.0/24.

Is that how it should be read? Or could someone interpret it as being one
summary, one route, covering both those networks. (160.0.0.0/7 ?)

Guess it would be something that I would ask the proctor about.

Subject: redistribute bgp into ospf when bgp synchronization is used

On R2, if I redistributed bgp into ospf, ospf will tell all the ospf routers
that R2 is the next hop. How can I tell ospf that the bgp router R1 is the
next hop? I tried using a route map to change the next hop in ospf but that
didn't work. R1 = 172.16.123.1, R2 = 172.16.123.2, R3 = 172.16.123.3 is one
of the ospf routers. r1, r2 and r3 are connected via frame-relay Broadcast.
The big question here is, can I manipulate info redistributed into ospf.
