Answer
# 1
1. Hints instructs the optimizer to generate the explain
plan as hinted rather than the optimizer choosing its own
explain plan..

2. There are many ways like disabling the index usage by
implementing a function or an operation on the indexed
column OR giving a FULL hint in the query for that
particular table etc
