instruction:
In this task you will be given a passage and a yes/no question based on the passage. You should answer the question using the information from the passage.
question:
passage: Not all functions have inverse functions. In order for a function f: X → Y to have an inverse, it must have the property that for every y in Y there must be one, and only one x in X so that f(x) = y. This property ensures that a function g: Y → X will exist having the necessary relationship with f.
 question: if a function is not one to one does it have an inverse?
answer:
No


question:
passage: A molecule is composed of one or more chemical bonds between molecular orbitals of different atoms. A molecule may be polar either as a result of polar bonds due to differences in electronegativity as described above, or as a result of an asymmetric arrangement of nonpolar covalent bonds and non-bonding pairs of electrons known as a full molecular orbital.
 question: can a molecule with nonpolar bonds be polar?
answer:
Yes
