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_pTTsG):
Solve for r: 160*r = 1600 Respond with an integer.

Question 1 (Question id: q_Vl8dXz8y):
Calculate 9 - 0.

Question 2 (Question id: q_b9li):
Calculate 3 / 3.

Question 3 (Question id: q_lwk6AzB):
Calculate 0 + 4 - 0.

Question 4 (Question id: q_O7Mp):
Determine the value of d that satisfies: 7*d + 13 = 90 Respond with an integer.

Question 5 (Question id: q_tzIf):
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: "and"



Output JSON where all question ids are keys, omitting q_tzIf.

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:
Include 'num_questions_asked' to record the total number of questions presented.
Provide 'questions_with_integer_answers', listing ids with integer answers (or [] if no integers).

Now provide the result JSON using the described format.
