Show me organization ids for organizations described as research
SELECT t1.organisation_id FROM Grants AS T1 JOIN Organisations AS T2 ON T1.organisation_id   =   T2.organisation_id JOIN organisation_Types AS T3 ON T2.organisation_type   =   T3.organisation_type WHERE T3.organisation_type_description   =   'Research'
organizations described as research refers to filtering where organisation_type_description = 'Research'; showing organization ids refers to selecting organisation_id; need to join tables Grants, Organisations, and organisation_Types to filter based on the description of the organization type.
