Final answer:
The proposal likely did not go well as altering a diamond can impact its brilliance and sparkle, affecting its appearance and value. The story context hints at an abundance of diamonds but does not detail the proposal's failure due to alteration.
Step-by-step explanation:
The question seems to be related to a story where a character named Kent proposes an alteration to a diamond, and the outcome is not positive. Given the context provided by the text excerpts, the proposal did not go well likely because modifying a diamond can significantly affect its brilliance and sparkle. Diamonds have a specific structure and the way they are cut and polished is designed to maximize the reflection of light. Removing a part of the diamond may disrupt this structure and reduce its desired visual properties, which is crucial for their value and appeal.
In the excerpts provided, there's a theme of discovering an immense amount of diamonds or individuals being unimpressed by them, rather than a specific mention of a flawed proposal due to alteration. Nevertheless, in line with general knowledge about diamonds, any proposed alteration risks diminishing the diamond's beauty and, consequently, its value. This context aligns with option A).
