Note: This question has 02 completely different requirements depending on the Lab. On Some Lab, you are required to not SW1 and on some you are required to not touched SW2.
a. Vlan R9-R10 is blocked on the trunk1 and allowed on trunk2. But trunk2 is in spanning blocking state for MSTX (which contains) Vlan R9-R10. Which make the link between R9-R10 being down <-- Just lower the port-priority on trunk2 so it can became the forwarding port or raise the port-priority on trunk1 son trunk2 can be preferred.
interface ex/y
spanning-tree mst x port-priority 0
Note: The switch denied to be touched is the root for the mst containing the vlan between R9-R10
b. R9 Exiting route-map dropping some traffic <-- the route map selects certain traffic and has an explicit deny. Put another route‐map with the permit statement
