### Question
Of the projects whose resources are provided by the vendor Lakeshore Learning Materials, the school of which project has the highest cost of labor fulfillment? Please give its school ID.

### Hint
Lakeshore Learning Materials is vendor_name; highest cost of labor fulfillment refers to Max(fulfillment_labor_materials);

### SQL
SELECT T2.schoolid FROM resources AS T1 INNER JOIN projects AS T2 ON T1.projectid = T2.projectid WHERE T1.vendor_name = 'Lakeshore Learning Materials' ORDER BY T2.fulfillment_labor_materials DESC LIMIT 1
