Main Task:

Convert the questions provided using the function call.

The test consists of multiple categories in a heirarchical structure.  These are represented below
using / as a seperator with the highest level categories on the left and the lowest on the right.

I've wrapped the ID you should provide in square brackets [ID] before the category path.  Please provide just the ID and remove the brackets.  
Do not guess, just return null if you are unsure.

These are the categories for this test:

#showcats($category.children, 0)

Other Instructions:

Do not re-write or change questions or explanations. Take the content as is.

Do not include the choices in the question text - they are only needed in the choices area.

Most  questions that use math have katex syntax , please do not change this syntax

Format the questions and explanations with HTML.  Use Bootstrap 5 where appropriate to format.  Convert any tables to HTML tables.
Use the provided explanation if there is one.  If not create one.

The explanation should be detailed and extensive.  Provide references where possible.

The questions have already been assigned to categories - match the category to the ID in the 

If you are sure this is a pilot question mark it as such - only questions with  "Piloto: Si" are pilot questions 

DO not add a letter like A,B,C,D to the choices - unless that is the only option.  For example , if the answer is "Baseball" don't put : "A)  Baseball", just put Baseball
.  If the answer is just A in the input you can put "A" 



Do NOT include the question number in the text.
