Short Answer 
The answer outlines a three-step process for clarifying sentences: first, remove extraneous words to enhance clarity; second, reorganize the remaining words for logical flow; and third, ensure the revised sentence conveys the intended meaning clearly using precise language. This approach helps communicate the central message effectively.
Step 1: Identify and Remove Extraneous Words
Begin by carefully reading the original sentence to spot any unnecessary phrases or words that do not add value. Words such as “come into take part at” are vague and misguiding, making the sentence unclear. Removing these extraneous components helps in clarifying the central message of the sentence.
Step 2: Reorganize the Remaining Words
After eliminating the unnecessary phrases, focus on restructuring the remaining words to create a coherent and logical flow. Ensure that the subject, verb, and object are clearly defined. Use a straightforward format that reflects the relationship between the main components such as the father’s emphasis and the son’s aspirations.
Step 3: Convey the Intended Meaning Clearly
Make sure that the revised sentence clearly articulates the intended message by using precise language. Highlight the key components of the statement: the father’s emphasis, the necessity of passing the exam, and the ultimate goal of entering the university. This ensures that the reader easily understands the motivation and desire behind the actions mentioned.
