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_NsgGWTnT):
How many times does the letter "u" appear in the text: "us then take"? Respond with an integer.

Question 1 (Question id: q_jyqXS):
Calculate 1 - -7 - 2.

Question 2 (Question id: q_h08J):
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: "event"



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_NsgGWTnT": {"answer": 1}, "q_jyqXS": {"answer": 6, "half_answer": 3}, "q_h08J": {"answer": "t"}}}
