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_yaaQTGa9):
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: "a"

Question 1 (Question id: q_acBRpXrQ):
Calculate ( ( ( ( ( ( 5 * 6 ) ) ) * 5 ) ) ).

Question 2 (Question id: q_HP4fNjKm):
Calculate -2 + -3 + 9.

Question 3 (Question id: q_6VuOY):
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 shrimps, 2 lobsters, 2 cows, 2 jellyfishs, 2 leechs?
 Respond with an integer.

Question 4 (Question id: q_nJoAg):
How many times does the letter "b" appear in the text: "Project Gutenberg electronic"? Respond with an integer.

Question 5 (Question id: q_FHUilYL):
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: "a"



Output JSON where all question ids are keys, omitting q_HP4fNjKm, q_yaaQTGa9.

The value for each key should be an object that contains the answer in the field 'answer'.
Include an 'answer_type' field (value 'string' or 'integer') for every answer object.
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.

Add a top-level 'global_metadata' field that records overall stats:
'num_questions_asked' should equal the total questions that appeared.
Add 'num_questions_answered' showing how many questions you answered.

Now provide the result JSON using the described format.
