### User's Query:
Which bond type accounted for the majority of the bonds found in molecule TR010 and state whether or not this molecule is carcinogenic?

### Extra Knowledge:
TR010 is the molecule id; majority of the bond found refers to MAX(COUNT(bond_type)); 
SELECT T.bond_type FROM ( SELECT T1.bond_type, COUNT(T1.molecule_id) FROM bond AS T1  WHERE T1.molecule_id = 'TR010' GROUP BY T1.bond_type ORDER BY COUNT(T1.molecule_id) DESC LIMIT 1 ) AS T
