Elyse is explaining to a friend that she will be conducting a scientific investigation. Her question is "How many leatherback sea turtles will migrate to their home beach on the eastern coast of Australia this season?" Elyse states
her hypothesis is "1,200 leatherback sea turtles will migrate to their home beach on the eastern coast of Australia this
season." For her procedure, she and a team of scientists will be observing and counting the number of turtles that land
on the beach. What is unusual about the description of her scientific investigation?

●intensive purposes is the correct answer

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.
