Answer:
The sentence that, if added to the passage, would best help the reader understand the meaning of the word "fossils" is:
3. Fossils are the hardened remains of plant or animal life from a previous geologic age.
Explanation:
When an author introduces a word in his writing that he believes the audience may not know, he can choose to include context clues to help the audience grasp its meaning.
<u>One type of context clue offers a definition of the word's meaning. That is the case with option 3. It provides the audience with a dictionary-like meaning of the word "fossils", helping them understand not only the word itself, but also the whole passage.</u>
The other options, even if not detached from the general idea of the passage, do not necessarily help the audience understand the meaning of "fossils". If the reader does not know the word's meaning already, adding any of these options will not at all help him grasp it.
Yes it can.
it is an exclamation so yes.
Persuasive writing is defined as "writing that attempts to convince the reader."
Narrative writing is a writing that tells a story. For example, autobiographies would be a narrative because they tell the story of a real person.
Expository writing is a writing that is used to explain, describe, or inform.
Problem-and-solution writing is a writing that well, states a problem and the solutions to it.
