Why is context important for the reader to determine the meaning of "kwashiorkor" in the excerpt?
Read the excerpt from The Boy Who Harnessed the
Wind by Wiliam Kamkwamba.
One Saturday, Gilbert met me in the library and we
flipped through books we thought might be fun. I
couldn't study all the time. One book that caught my
attention was the Malawi Junior Integrated Science
book, used by Form Four students. Hmm, I thought,
and flipped it open. There were lots of pictures and
diagrams, which I found easy to understand. I saw
pictures of cancer and scabies and children stricken
with kwashiorkor, like so many who'd wandered the
country. One picture had a man in a shiny silver suit
walking on the moon.
O The context makes it easier for the reader to make

O The context clarifies unfamiliar words in the text for
the reader.
O The context shows the reader why certain events
are important.
O The context provides the introduction to the text.

This question is incomplete because the excerpt is missing; here is the excerpt:

In a smithy   one sees a white-hot axehead or an adze  plunged and wrung in a cold tub, screeching steam-  the way they make soft iron hale and hard—: just so that eyeball hissed around the spike.

The answer to this question is D. How hot the spear actually is

Explanation:  

The purpose of the epic simile is to make an extensive comparison between two elements of ideas. This differs from regular simile because it uses many details or lines to make the comparison. In the excerpt presented, the author uses an epic simile to compare the actin of the spike entering the eye of the cyclops with the action of putting a hot metal in a cold tub through details such as "white-hot axehead... in a cold tub" or "that eyeball hissed around the spike". Moreover, the purpose of using this epic simile is to emphasize how hot the spike is, which allows the reader to imagine the reaction of the cyclops as the hot spike enters its eye.
