How to show a table based on a dropdown selection

So lets say I have a cell in which the user has to select from a drop down menu a value from 1-10.
Based on this selection I want the user to get presented a fully formatted table with additional dropdown menu's

For example the user selects 2. He will be shown a table with 2 columns, and two rows showing in the first column Q1 and another drop down menu in the second column. And under that Q2 with a second drop down menu.
If he selects 3 this will be 3 columns and 3 rows etc.

As this is an example, it's fine that this would be hardcoded. 4 could give the same table as 2 or 5 might give just one addition question. I just want to know how I could change the presented table when a different entry is selected in the dropdown menu.

Finally I would like to know how to give information about the selection.

Let's say I selected 2 and the answer to Q1 is a name 'Arnold' I then would like in a different table to show information about the selection 'Arnold' (stuff like age, married yes/no, kids yes/no etc.)

If you know any way of doing this, please let me know.

Sorry for not being able to explain it better, I included a mockup sheet. Hope it helps!

Beautiful! It seems to be working like I want it to, except for two things:
1) Whenever you lower the amount of people, it will keep the same amount of drop down menu's. Is there a way to not make this show up? I could just hide this 'system' and only show the parts I want to be shown in a different sheet, but I would prefer it to work all in the same sheet.
2) the formatting stays the same. I would prefer when you select '4' only the 4 relevant rows are formatted (in this case, blue) this is just a minor cosmetic issue, so shouldn't be a big problem, but in case it has an easy solution I would prefer it over this.

But for now, a huge thanks! You really helped me a lot!

Don't worry, have a save trip
