Your first question was closed as "unclear". You say in your comment that you don't think it's unclear, so lets review:
My uncle called different law firms to compare. Every lawyer who spoke
with him, asked if he were shopping around and had called other law
firms. Assume malevolent nosy intent by lawyers, probably to decide
how much help and time to spend on you. I ask not about benevolent
intent because then answering 'yes' is the easy solution.
None of the 3 possible answers appear tactful:
answering 'no' would be lying. Yet a lawyer who believes that you're not shopping around, may be less deceiving about true fees
(thus averting distressing negotiation) or work harder to lower it (by
asking her manager).
answering 'yes' is truthful. But a yes' (even if lawyers expect shopping around) may estrange or repel lawyers and cause them to help
you less, because why would a lawyer spend time with you if you
haven't offered any commitment?
refusing to answer appears brusque and suspicious, and shortsighted because a clever lawyer can divine from your silence that
you're truly shopping around.
This is after your third edit, so I'm using the most up to date version possible of your question for comparison. This question doesn't contain a clear problem statement. You don't specify what you want an answer to address. There is something like a question in the title, but it's not reflected in the question body and pretty broad and general.
The answer it got is a good indication of this, as it doesn't really answer your question per say, it more challenges the frame of your question. That means it's not offering an interpersonal solution to your interpersonal problem, but giving you general life advice in the face of a vague problem that isn't specifically made interpersonal. (The answer is talking to you about sales tactics and market positions, not about how to socially interact with the people you're calling)
As for improving it, I suggest reforming your problem statement to have a specific clear interpersonal goal you want to achieve, and to trim down the details to necessities.
As for why it was deleted, I can only speak for myself (I was one of the three delete voters on that question).
The question was closed on November 12, 2017. That was more then 10 days before it was deleted, giving you plenty of time to fix issues with the question and get it reopened. If a question of yours is closed, it is generally a call for you to improve it to fix the issues the closure highlighted. You made one edit on November 17, 2017 that in my opinion didn't address the core issues with the question at all (there is no real problem statement and the one in the title is open ended and broad).
Ultimately, this isn't helpmewithanyproblemeverwithanysolutionyouwanttosuggest.SE, it's Interpersonal.SE. I thought it unlikely for this question to become on topic after several edits and a completed reopen review and 12 days of closure, I voted to delete it.
I didn't vote to delete your second question, so I'll leave the explaining of that one to the people who did.
