### Question
Please list the names of all the suppliers for parts under Brand#55.

### Hint
supplier name refers to s_name; Brand#55 refers to p_brand = 'Brand#55'

### SQL
SELECT T3.s_name FROM part AS T1 INNER JOIN partsupp AS T2 ON T1.p_partkey = T2.ps_partkey INNER JOIN supplier AS T3 ON T2.ps_suppkey = T3.s_suppkey WHERE T1.p_brand = 'Brand#55'
