"The person reads a newspaper."
Translation:Die Person liest eine Zeitung.
It is neither of those -- it is die Person (with capital P).
The grammatical gender of a noun does not, in general, have anything to do with the natural gender of the object that the noun refers to. It's just something that you have to learn.
das Messer is neuter, die Gabel is feminine, der Löffel is masculine, even though knives, forks, and spoons are neither male or female.
Similarly, die Person is feminine (even though persons can be male or female) and das Mädchen is neuter (even though girls are female), etc.
Learn the gender of a noun together with a noun; trying to deduce it through "logic" will usually not work.
