**(2)** **Charitable contributions** The deduction for charitable contributions and gifts allowed by section 170.

**(3)** **Personal exemption** The deduction for personal exemptions allowed by section 151, except that only one exemption shall be allowed under section 151 unless the taxpayer is a resident of a contiguous country or is a national of the United States.
