how does the author organize information in this article to create a clear main idea? a. chronologically b. interviews and research c. cause and effect d. problem-solution

The correct answer is A. Chronologically.

Explanation

According to the information in the question, it can be affirmed that the author wrote the information in chronological order because it coincided with the birth of Gertrude Belle Elion in 1918, later referring to the title in biochemistry that she obtained in 1937. Then It refers to the multiple works that she carried out in parallel that she was studying to obtain the master's degree in 1941. As a reference, it has three dates that are ascending, so it can be said that the writing is chronological. So, the correct answer is A.

sentences vary by structure as well as by function. there are compound, complex, and compound-complex sentences.

simple sentence

i like to read.

a simple sentence has one independent clause.

compound sentence

i like to read, and i also like to write.

a compound sentence includes more than one independent clause, connected by a coordinating conjunction (and, but, for, nor, or, so, or yet).

complex sentence

i prefer to read books that are bestsellers.

a complex sentence includes one independent clause and one or more dependent clauses. (a dependent clause is one that cannot stand alone.) types of dependent clauses include relative clauses (i kicked the boy who pinched me), adverb clauses (i am going home now because i have a curfew), and noun clauses (i don't know what to do next).

compound-complex sentence

although i prefer to read current bestsellers, i do like to read old agatha christie mysteries, and i also like some 20th-century science fiction.

compound-complex sentences take a bunch of clauses (multiple independent clauses, and one or more dependent clauses) and toss them together like a salad. although these sentences take practice to write in a grammatically correct fashion, they can hold a tremendous amount of meaning, and are common in academic writing.
