Final answer:
Valerie needs to eliminate redundancies to make her proposal more accurate and also watch out for miscalculations. While not always necessary to remove, passive voice and prepositional phrases should be evaluated for clarity and effectiveness.
Step-by-step explanation:
If Valerie's boss is reviewing her proposal and tells her she needs to make it more accurate, the element she should try to eliminate is redundancies. When writing, it's important to be concise and eliminate unnecessary words to ensure clarity and precision. Redundancies tend to be filler content that does not add meaningful information to the text. On top of that, Valerie should pay attention to miscalculations, as these can significantly detract from the accuracy of her proposal. Additionally, while it may not be necessary to eliminate prepositional phrases entirely, they should be used effectively to avoid confusion.
A common piece of advice is to avoid using the passive voice when not necessary, as active voice brings clarity and vitality to writing. However, it's important to note that sometimes passive voice is preferable, such as when the doer of the action is unknown or the object being acted on is more important than the doer. Thus, while editing for clarity and conciseness, Valerie should still consider the purpose of each sentence and the effect she intends to create before converting passive constructions into active voice.
