Hebert argues that contemporary (modern) maps are “…as biased and conventional as ever.” – how does she justify this point of view?

Hebert's claim that contemporary (modern) maps are "...as biased and conventional as ever".

She justified this point of view that she claimed because she thinks mapmakers have too much freedom and power, and that mapmakers display what they want, how they want and no one questioned them. They are free to do whatever they want. 

The figure is not necessarily a parallelogram because only one diagonal is bisected and only one pair of sides is congruent.

Magma forms by partial melting of upper mantle and crust. partial melt means that only a fraction of the available material forms a melt, and that the remainder stays solid. the partial melt rises because of its lower density and ascends through he crust. this is so conclusive mean the answer would be magma igneous rocks or balistic magma.
