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_4fRjSJ0):
Determine the value of i that satisfies: 140*i - 6 = 1254 Respond with an integer.

Question 1 (Question id: q_RCzYTPsJ):
Calculate -7 * 0 + 0.

Question 2 (Question id: q_bV7G):
Find the value of f in the equation: -5*f - 30 = -70 Respond with an integer.

Question 3 (Question id: q_7VallB):
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: "the"



Create a JSON object keyed by every question id except q_bV7G.

For every question id, supply an object whose 'answer' field stores the solution.
Also add the answer type as 'string' or 'integer' to the field 'answer_type' for each 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.
If the question asks for the last character of a string, add an 'original_string' field containing the source string.

Now provide the result JSON using the described format.

{"ground_truth": {"q_RCzYTPsJ": {"answer": 0, "answer_type": "integer", "half_answer": 0}, "q_7VallB": {"answer": "e", "answer_type": "string", "original_string": "the"}, "q_4fRjSJ0": {"answer": 9, "answer_type": "integer"}}}
