Here is a set of basic questions producing integer or string outputs. Answer them and format the result precisely with the JSON instructions provided:

Question 0 (Question id: q_TDVGf1):
Determine the value of x that satisfies: 20 - 6*x = 2 Respond with an integer.

Question 1 (Question id: q_FAImz8s):
Your job is to return the last character of a string as a string. For example, the last char of "hello" is "o". Return the last character of the following string: "money"

Question 2 (Question id: q_8gu3Yqv):
Calculate 6 - 4 + 6.

Question 3 (Question id: q_WGaJ4):
Determine the value of m that satisfies: 130 - 10*m = 90 Respond with an integer.

Question 4 (Question id: q_ECqR5m):
How many times does the letter "b" appear in the text: "problems with her"? Respond with an integer.



Return a JSON with each question id as a key.

The value for each key should be an object that contains the answer in the field 'answer'.
For even integer answers, include 'half_answer' equal to answer ÷ 2.
For string answers, include 'first_char' with the answer’s initial letter.

Add a top-level 'global_metadata' field that records overall stats:
'num_questions_asked' should equal the total questions that appeared.

Now provide the result JSON using the described format.
