Can you list the name and membership amount of the branch that had the least amount of memberships that were opened in the year 2017?
SELECT name, membership_amount FROM branch where membership_amount  =   ( select min ( membership_amount )  from branch where open_year like "%2017%" ) 
least amount of memberships = MIN(membership_amount); memberships opened in the year 2017 refers to open_year LIKE '%2017%';
