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_2v9y):
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 1 (Question id: q_dzAG):
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: "hoping"

Question 2 (Question id: q_rYt1Z):
How many times does the letter "e" appear in the text: "799 642 miles"? Respond with an integer.

Question 3 (Question id: q_Bebi8y):
Determine the value of a that satisfies: 26*a = 494 Respond with an integer.

Question 4 (Question id: q_WzsRf):
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 1 firefly, 4 humans, 1 cow?
 Respond with an integer.

Question 5 (Question id: q_qKpFxZd):
Solve for q: 260*q - 480 = 560 Respond with an integer.



Create a JSON object keyed by every question id except q_2v9y.

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, add the field 'additional_answer_info' containing 'half_answer' (answer ÷ 2) and 'double_answer' (answer × 2).

Now provide the result JSON using the described format.

{"ground_truth": {"q_WzsRf": {"answer": 18, "additional_answer_info": {"half_answer": 9, "double_answer": 36}}, "q_Bebi8y": {"answer": 19}, "q_rYt1Z": {"answer": 1}, "q_dzAG": {"answer": "g"}, "q_qKpFxZd": {"answer": 4, "additional_answer_info": {"half_answer": 2, "double_answer": 8}}}}
