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_W7VFjhOF):
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: "planet"

Question 1 (Question id: q_cqzG4RA):
Determine the value of r that satisfies: 14*r - 10 = 60 Respond with an integer.



Return a JSON with each question id as a key.

The value for each key should be an object that contains the answer in the field 'answer'.
For even integer answers, include 'half_answer' equal to answer ÷ 2.

Now provide the result JSON using the described format.

{"ground_truth": {"q_W7VFjhOF": {"answer": "t"}, "q_cqzG4RA": {"answer": 5}}}
