Final answer:
To limit a long lead-in and create a more concise sentence, unnecessary words should be cut, and the sentence should directly convey its main message. Maintaining consistency in verb tense and using subjects that perform actions can also enhance clarity. Hence, the correct answer is option 3.
Step-by-step explanation:
The question concerns how to revise a sentence to make it more concise, specifically focusing on eliminating a long lead-in in sentence 3. To limit a long lead-in and create a more concise sentence, one strategy is to cut out unnecessary words and get straight to the point.
For instance, turning a sentence like 'So that you know in the future, we should be more careful about scheduling.' into a more direct statement such as 'In the future, we should be more careful about scheduling.' removes the excess and focuses on the main message.
Consistency in verb tense is also important for clarity, as is replacing impersonal constructs like 'There is' or 'There are' with a subject that performs an action. The goal is to engage the reader with clear, direct, and meaningful writing.
