The literary device that provides clues or hints to suggest what will occur later in a story is called: O Allusion
O Foreshadowing
O Flashback
O Metaphor

B). Foreshadowing.

Explanation:

Foreshadowing is demonstrated as the literary device that the authors employ to provide a hint or clue to the readers that would indicate a future event or action that is going to take place in the plot of the story. It primarily assists the author in developing dramatic tension or creating suspense as the readers are uncertain and keep guessing and anticipating what would happen next. This helps in arousing the interest of the audience or readers' and elicit the desired reactions and feeling from them.

For example, In Shakespeare's famous love story 'Ro-m-eo and Ju-lie-t', he provides a clue of Ro-m-eo's ultimate destiny(his commitment of sui-cide) through his statement: “My life were better ended by their hate, than death prorogued, wanting of thy love."

foreshadowing

Explanation:

the correct answer is option d. none of these. it is noted that options a, b, and c share the same content.

despite the valid answer provided at the last sentence of each of the options, a question/answer format shouldn't include humourous themed responses such as "you bet your thermal pj's we do." - unless of course, the answer is carried out in an informal environment. this could be replaced with a simple "yes" or "it is necessary".

the question should be re-phrased to a more appropiate syntaxis. instead of "do we need the greenhouse effect? ", it should be written as "is the greenhouse effect necessary? " in order to give it a general scope, instead of limiting the answer to the needs of "we" the humans.
