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_2F3Hu):
Find the value of r in the equation: 640*r = 3200 Respond with an integer.

Question 1 (Question id: q_2TFkv):
Determine the value of n that satisfies: 10 - 6*n = -80 Respond with an integer.

Question 2 (Question id: q_hzNK8Nx):
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: "their"

Question 3 (Question id: q_5gBnpOj):
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: "try"

Question 4 (Question id: q_g1R7Fv1):
Calculate -2 * -6 + 0.

Question 5 (Question id: q_USEN):
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: "to"

Question 6 (Question id: q_ro7j):
Your task is to count how many legs there are in total when given a list of animals.

Now, how many legs are there in total if you have 4 sheeps, 4 cats, 3 lions, 4 grasshoppers, 3 chickens?
 Respond with an integer.

Question 7 (Question id: q_ca6XoNJp):
Solve for k: 27*k - 10 = 314 Respond with an integer.

Question 8 (Question id: q_ldtA5qW):
Calculate ( 7 - 2 ).

Question 9 (Question id: q_I7H1):
Your task is to count how many legs there are in total when given a list of animals.

Now, how many legs are there in total if you have 3 chickens, 3 grasshoppers, 2 cows, 3 wasps, 3 spiders?
 Respond with an integer.

Question 10 (Question id: q_WEfV):
Your task is to count how many legs there are in total when given a list of animals.

Now, how many legs are there in total if you have 4 cows, 1 starfish, 3 wasps?
 Respond with an integer.

Question 11 (Question id: q_E5nXb):
Calculate 0 - 9 * -6.



Return a JSON with each question id (except for q_I7H1, q_E5nXb, q_hzNK8Nx, q_USEN) as a key.

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.
For string answers, include 'first_char' with the answer’s initial letter.
For last-character tasks, provide 'original_string' alongside the answer.

Add a top-level 'global_metadata' field that records overall stats:
'num_questions_asked' should equal the total questions that appeared.
'questions_with_integer_answers' should enumerate every id whose answer is an integer.

Now provide the result JSON using the described format.
