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_GdRB):
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 1 (Question id: q_a1EZV3LU):
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: "each"

Question 2 (Question id: q_jSys):
How many times does the letter "l" appear in the text: "I shall"? Respond with an integer.

Question 3 (Question id: q_LETg):
Calculate 9 + ( 7 + 5 ).

Question 4 (Question id: q_ljmP):
How many times does the letter "t" appear in the text: "particular paper"? Respond with an integer.



Your output must be a JSON mapping every question id to its answer info.

For every question id, supply an object whose 'answer' field stores the solution.
For even integer answers, include 'half_answer' equal to answer ÷ 2.

Now provide the result JSON using the described format.

{"ground_truth": {"q_GdRB": {"answer": "d"}, "q_a1EZV3LU": {"answer": "h"}, "q_jSys": {"answer": 2, "half_answer": 1}, "q_LETg": {"answer": 21}, "q_ljmP": {"answer": 1}}}
