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_8UhBMK7):
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: "enough"

Question 1 (Question id: q_jPbfPZ):
How many times does the letter "h" appear in the text: "posted on the"? Respond with an integer.

Question 2 (Question id: q_amtC):
Determine the value of q that satisfies: 7*q + 3 = 122 Respond with an integer.

Question 3 (Question id: q_ilwKs):
How many times does the letter "r" appear in the text: "trademark It"? Respond with an integer.

Question 4 (Question id: q_up6F3j8K):
Calculate ( 5 - 2 ) - -3.



Produce a JSON object whose top-level keys are the question ids.

For every question id, supply an object whose 'answer' field stores the solution.
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 response to a question is a string, add a 'first_char' field containing its first character.

Beyond the question-id fields, add a 'global_metadata' object with summary information:
• num_questions_asked – total number of questions originally shown.

Now provide the result JSON using the described format.
