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_dZWW5yiw):
Calculate -7 * -4 / 1.

Question 1 (Question id: q_0u2m):
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"

Question 2 (Question id: q_T7BT3sN):
Calculate ( 0 - -4 ).

Question 3 (Question id: q_RMklkMkx):
Calculate 6 * 5.

Question 4 (Question id: q_QE7nZB):
Determine the value of v that satisfies: 60*v = 480 Respond with an integer.

Question 5 (Question id: q_GN2yurG):
Calculate 5 + 8.

Question 6 (Question id: q_LFerFOv):
How many times does the letter "r" appear in the text: "arms at"? Respond with an integer.

Question 7 (Question id: q_QvLl):
How many times does the letter "e" appear in the text: "will be"? Respond with an integer.



Return a JSON with each question id as a key.

The value for each key should be an object that contains the answer in the field 'answer'.
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:
'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.
