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_7PVs8):
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: "about"

Question 1 (Question id: q_9Ekd92sQ):
Calculate 5 * 8.

Question 2 (Question id: q_iHt0eamS):
Calculate -2 + 4.

Question 3 (Question id: q_JFDE6M):
Calculate -4 * -8 + -9.

Question 4 (Question id: q_v5Zz4qC):
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: "of"

Question 5 (Question id: q_GNxVEyY):
How many times does the letter "e" appear in the text: "electronic works in"? Respond with an integer.

Question 6 (Question id: q_loZI):
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 7 (Question id: q_ftgXtq):
Calculate 9 - 0 + 6.



Create a JSON object keyed by every question id except q_loZI, q_GNxVEyY.

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 last-character tasks, provide 'original_string' alongside the answer.

Now provide the result JSON using the described format.

{"ground_truth": {"q_iHt0eamS": {"answer": 2, "half_answer": 1}, "q_ftgXtq": {"answer": 15}, "q_7PVs8": {"answer": "t", "original_string": "about"}, "q_v5Zz4qC": {"answer": "f", "original_string": "of"}, "q_9Ekd92sQ": {"answer": 40, "half_answer": 20}, "q_JFDE6M": {"answer": 23}}}
