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_zjUMLA19):
Find the value of d in the equation: 15*d - 13 = 152 Respond with an integer.

Question 1 (Question id: q_eaDHeVSf):
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: "understand"



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

Each key’s value must be an object holding an 'answer' field.
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.

Add a top-level 'global_metadata' field that records overall stats:
Include 'num_questions_asked' to record the total number of questions presented.
• questions_with_integer_answers: ids of questions with integer replies.

Also include 'combined_results' consisting of:
  • integer_info: per-id integer answers
  • sum_of_answers: their total

Now provide the result JSON using the described format.
