How many terms are in the expression shown? 2n + 5 – 3p + 4n

There are 4 terms in the expression "as is", namely 2n, +5, -3p, +4n.
HOWEVER, questions of this nature is usually to test the ability of students to recognize the possibility of simplification, which in this case results in 
2n+5-3p+4n=6n+5-3p
The simplified expression has three terms.  I believe the expected answer is three terms, but depending on the context, "the expression shown" has actually 4 terms.
