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_Hjat):
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: "by"

Question 1 (Question id: q_T2hHv):
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: "growth"

Question 2 (Question id: q_807oPwj4):
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 4 giraffes, 1 sheep, 2 elephants, 4 tigers?
 Respond with an integer.

Question 3 (Question id: q_dhDKtwO):
How many times does the letter "n" appear in the text: "nearly any"? Respond with an integer.

Question 4 (Question id: q_rxHYSr):
Solve for r: 4*r - 9 = 19 Respond with an integer.



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

Each key’s value must be an object holding an 'answer' field.
For even integer answers, include 'half_answer' equal to answer ÷ 2.
For last-character tasks, provide 'original_string' alongside the answer.

Now provide the result JSON using the described format.

{"ground_truth": {"q_rxHYSr": {"answer": 7}, "q_T2hHv": {"answer": "h", "original_string": "growth"}, "q_807oPwj4": {"answer": 44, "half_answer": 22}, "q_Hjat": {"answer": "y", "original_string": "by"}}}
