Total Columns: 11

Table Schemas:

Table: atom (3 columns)
-----------------------
• atom_id (text): the unique id of atoms
• molecule_id (text): identifying the molecule to which the atom belongs
  Values: commonsense evidence:
TRXXX_i represents ith atom of molecule TRXXX
• element (text): the element of the toxicology
  Values:  cl: chlorine
 c: carbon
 h: hydrogen
 o: oxygen
 s: sulfur
 n: nitrogen
 p: phosphorus
 na:...

Table: bond (3 columns)
-----------------------
• bond_id (text): unique id representing bonds
  Values: TRxxx_A1_A2:
TRXXX refers to which molecule
A1 and A2 refers to which atom
• molecule_id (text): identifying the molecule in which the bond appears
• bond_type (text): type of the bond
  Values: commonsense evidence:
-: single bond
'=': double bond
'#': triple bond

Table: connected (3 columns)
----------------------------
• atom_id (text): id of the first atom
• atom_id2 (text): id of the second atom
• bond_id (text): bond id representing bond between two atoms

Table: molecule (2 columns)
---------------------------
• molecule_id (text): unique id of molecule
  Values: "+" --> this molecule / compound is carcinogenic
'-' this molecule is not / compound carcinogenic
• label (text): whether this molecule is carcinogenic or not

##Evidence:
label = '+' mean molecules are carcinogenic; element = 'cl' means Chlorine; element = 'c' means Carbon; element = 'h' means Hydrogen; element = 'o' means Oxygen, element = 's' means Sulfur; element = 'n' means Nitrogen, element = 'p' means Phosphorus, element = 'na' means Sodium, element = 'br' means Bromine, element = 'f' means Fluorine; element = 'i' means Iodine; element = 'sn' means Tin; element = 'pb' means Lead; element = 'te' means Tellurium; element = 'ca' means Calcium

##Role Access Policy (Column-Level):
Role: MolecularDataEntry
Accessible Columns: molecule: molecule_id, label; atom: atom_id, molecule_id, element; bond: bond_id, molecule_id, bond_type

Based on the above schema and your role's column-level access policy, generate a SQL query to answer the question. If your role does not have access to the required columns, respond with: "Sorry, I cannot answer."


Question: List all carcinogenic molecules and their elements.
Evidence: label = '+' mean molecules are carcinogenic; element = 'cl' means Chlorine; element = 'c' means Carbon; element = 'h' means Hydrogen; element = 'o' means Oxygen, element = 's' means Sulfur; element = 'n' means Nitrogen, element = 'p' means Phosphorus, element = 'na' means Sodium, element = 'br' means Bromine, element = 'f' means Fluorine; element = 'i' means Iodine; element = 'sn' means Tin; element = 'pb' means Lead; element = 'te' means Tellurium; element = 'ca' means Calcium
Answer: SELECT DISTINCT T2.molecule_id, T1.element FROM atom AS T1 INNER JOIN molecule AS T2 ON T1.molecule_id = T2.molecule_id WHERE T2.label = '+'
