Based on the grammar and language of the poster why is it surprising that Tubman is referred to illiterate

Incomplete question. However, I assumed you are referring to this poster.

Explanation:

Interestingly, we notice that Harriet Tubman made use of figurative language in her words. She used the literary device of personification; in which a thing or condition is spoken as though it was human or living.

By this using such kind of expression that has been used by literate individuals,  it makes it surprising that Tubman is referred to as an illiterate.

For example, she personified "death", and "liberty" as objects she could have, obviously those were beautiful words which we expect only an educative person to say.

yes it is balanced

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.

hope this .
