How do people know which direction to read hieroglyphs?

Hieroglyphs can actually be read in almost any direction: left to right, right to left, and top to bottom. To determine how to read a specific set of glyphs, start by locating a glyph with a head. If the head is facing to the left, start reading from the left and work you way towards the head.

Explanation:

there are no options provided but you can choose among the following gender-neutral pronouns: zir, hir, eir, vis, tem, eir.

in the normal course of maintaining a pronoun-antecedent agreement, we could have used the words his or her but since we are also required to use gender-neutral language, we need to replace it with its equivalent gender-neutral pronoun.
