CREATE TABLE authors (authid DECIMAL, lname TEXT, fname TEXT)
CREATE TABLE inst (instid DECIMAL, name TEXT, country TEXT)
CREATE TABLE papers (paperid DECIMAL, title TEXT)
CREATE TABLE authorship (authid DECIMAL, instid DECIMAL, paperid DECIMAL, authorder DECIMAL)

Which paper has the most authors? Give me the paper title.
SELECT t2.title FROM authorship AS t1 JOIN papers AS t2 ON t1.paperid = t2.paperid WHERE t1.authorder = (SELECT MAX(authorder) FROM authorship)
SELECT "t2"."title" FROM "authorship" AS "t1" JOIN "papers" AS "t2" ON "t1"."paperid" = "t2"."paperid" WHERE "t1"."authorder" = (SELECT MAX("authorder") FROM "authorship")
