Why don t I have any questions!!!!!!

Some questions are not answered for the following reasons:

1) The questioner is not very polite.

Such as "Quick, give it to me!" ”

2) Too many questions at once.

There's a math problem, and I can't wait to copy the whole paper.

3) The question is incomplete.

Let others see it, and I don't know what I'm going to do.

4) The problem is too obscure.

5) Suspected violations.

Such as unsigning, superstition and other content, others are worried about being deleted by the system.

6) Obvious hype or knowingly asking.

7) The problem is too big and it is not good for people.

8) The question is not in the right section.

Generally speaking, there are similar questions in the section.

9) The questioner's narration skills are important.

The general question is based on the principle of conciseness and clarity.

10) Don't get involved in cutting-edge science.

If even scientists don't have the answer, it's hard to come up with an answer here.

11) The question asked does not match the reward points.

Admittedly, the bounty points, as well as the politeness of the questioner, are attractive to the person asking the question, but not all. Sometimes, I spend half a day dedicating to other people's problems, and it's important that I really want to help others.

12) Asking questions is too boring.

13) Asking questions that are too shallow.

Why is there no one to ask too shallowly, because everyone is thinking, such a simple question, others will, will definitely be in front of me, so it is not the same.

I hope it can help you and solve your problem as soon as possible.

B was originally in the single digit, but now it is adjusted to the thousand, so multiply B by 1000, that is, the digit remains unchanged after 1000Ba, that is, A.

The final result is 1000b+a

So choose D. If you still don't understand, you can set the number to find: the original number is 12345, and the adjusted number is 45123, which can be solved by using the above principle.

Because A is a three-digit number and B is a two-digit number, and the two-digit number B needs to be multiplied by 1000 to become a 5-digit number, so the answer is D

The remaining 1 gram of AD may be hydrogen or oxygen.

A because the mass ratio of hydrogen to oxygen in water is 1:8

So choose A
