In the following English grammar question on voice, choose the correct active form of the sentence: A good deal of money will be made by that investment.

Introduction / Context:
This question evaluates your understanding of transforming a simple future passive sentence into its active counterpart. The given sentence is A good deal of money will be made by that investment. Here, the focus in the passive structure is on the result (money made) rather than on the source (that investment). In active voice, we want to shift the focus back to the investment that generates the money while keeping the future tense and meaning unchanged.

Given Data / Assumptions:

• Passive sentence: A good deal of money will be made by that investment.
• Agent / doer: that investment.
• Verb phrase: will be made (simple future passive).
• Object (in passive subject position): a good deal of money.
• Task: Choose the active sentence that preserves tense and meaning.

Concept / Approach:
For simple future tense, the passive pattern is will be + past participle. The corresponding active form is will + base verb. Here, will be made must become will make. The subject in the passive, a good deal of money, becomes the object in the active, while that investment becomes the subject. Thus the active-voice sentence is That investment will make a good deal of money. No change is made to the expression a good deal of money, and the future time reference (will) is preserved.

Step-by-Step Solution:

Verification / Alternative check:
To verify, mentally convert the chosen active sentence back into passive: A good deal of money will be made by that investment. This matches the original sentence exactly, confirming that the tense, agent, and result are the same. The phrase a good deal of money keeps its meaning of a large amount of money, and will make matches will be made in future time reference.

Why Other Options Are Wrong:
Option A (That investment has made a good deal of money.) changes the tense to present perfect has made, which indicates a completed action in the past rather than a future outcome. Option B (That investment will be making a good deal of money.) uses the future continuous will be making, which suggests an ongoing process rather than a simple future result. Option C (That investment has been making a good deal of money.) uses present perfect continuous, again changing the time reference. Option E (That investment made a good deal of money last year.) switches to simple past and even introduces last year, extra information not given in the original sentence.

Common Pitfalls:
Candidates often change the tense unintentionally while transforming voice, especially with the auxiliary will. Another pitfall is to confuse simple future with future continuous or with various perfect tenses, which subtly change the time frame and aspect. Some learners also treat a good deal of money as a countable phrase and try to alter it, but it is already correct and idiomatic. The safest approach is to keep the time marker will, preserve the amount phrase exactly, and focus on swapping the roles of subject and object correctly.

Final Answer:
The correct active-voice transformation is That investment will make a good deal of money.
