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_O4Dk5fvG):
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: "the"

Question 1 (Question id: q_D4hOBgn):
How many times does the letter "t" appear in the text: "to donate"? Respond with an integer.

Question 2 (Question id: q_I75v):
Solve for r: 6 - 4*r = -74 Respond with an integer.



Your output must be a JSON mapping every question id to its answer info.

For every question id, supply an object whose 'answer' field stores the solution.
Include an 'answer_type' field (value 'string' or 'integer') for every answer object.
If the response to a question is an integer that is even, also add the field 'half_answer' to the object which contains the answer integer divided by two.
If the question asks for the last character of a string, add an 'original_string' field containing the source string.

Add a top-level 'global_metadata' field that records overall stats:
• num_questions_asked: how many questions were asked in total.
• num_questions_answered: count of questions present in your JSON.

Now provide the result JSON using the described format.
