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_rc9vM):
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: "flows"

Question 1 (Question id: q_RCp2g8Se):
Calculate -1 * ( -3 / 1 ).

Question 2 (Question id: q_evK1U5x):
How many times does the letter "t" appear in the text: "another examination A"? Respond with an integer.

Question 3 (Question id: q_DhDnx):
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: "not"

Question 4 (Question id: q_sztzf2Cr):
Calculate 6 + 5.



Create a JSON object keyed by every question id except q_evK1U5x.

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

Now provide the result JSON using the described format.

{"ground_truth": {"q_sztzf2Cr": {"answer": 11, "answer_type": "integer"}, "q_DhDnx": {"answer": "t", "answer_type": "string", "first_char": "t"}, "q_RCp2g8Se": {"answer": 3, "answer_type": "integer"}, "q_rc9vM": {"answer": "s", "answer_type": "string", "first_char": "s"}}}
