Final answer:
The statement indicating that puddles took a long time to drain is 'The puddles drained slowly.' The short-to-long principle is best exemplified in a sentence discussing teacher's actions. Drag force related expressions and water flow in wetlands are explained with correct examples.
Step-by-step explanation:
The statement that indicates that puddles took a long time to drain is option 3, 'The puddles drained slowly.' This statement directly implies that the process of the puddles draining was not quick, hence it took a considerable amount of time. When you are trying to express that something is taking longer than usual or expected, phrases like 'drained slowly' are appropriate to convey the sense of prolonged duration.
In order to illustrate the use of the short-to-long principle, sentence 4 is a correct example. 'The upset teacher decided to punish all the students who were late. He did not distinguish between the students who had not turned in the assignment on the due date and the ones who had completed the assignment.' This sentence moves from a shorter concept to a longer, more complex one, allowing the reader to digest information more effectively.
Regarding the conversion of sentences from active to passive voice, let's look at this example: 'My car was broken into last night.' The passive construction conveys what happened, but the subject who performed the action is omitted or unknown.
