Pick the correct sentence.
Answer:
D. The boy worked hard on his story, for he wanted to win the contest.
Explanation:
A compound sentence is any sentence composed of two independent clauses, separated by a comma and a conjunction (for, and, nor, but, or, yet, so) or a semicolon. The two independent clauses in answer D are "The boy worked hard on his story" (subject being boy, verb being worked), and "he wanted to win the contest" (subject being he, verb being wanted).
Answers A and B are incorrect because they do not contain two independent clauses. C also does not contain two independent clauses, but instead a prepositional phrase, which could be confused with an independent clause. These are not the same however, and the comma separating this phrase and clause is not followed by a conjunction word, therefore it is not a compound sentence.
I hope this helps! Happy learning, friend :)
Explanation:
A blueprint is a reproduction of a technical drawing or engineering drawing using a contact print process on light-sensitive sheets. Introduced by Sir John Herschel in 1842,[1] the process allowed rapid and accurate production of an unlimited number of copies. It was widely used for over a century for the reproduction of specification drawings used in construction and industry. The blueprint process was characterized by white lines on a blue background, a negative of the original. The process was not able to reproduce color or shades of grey.

The process is now obsolete. It was first largely displaced by the diazo whiteprint process, and later by large-format xerographic photocopiers.
The term blueprint continues to be used less formally to refer to any floor plan[2] (and even less formally, any type of plan).[3][4] Practicing engineers, architects, and drafters often call them "drawings" or "prints".
