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_Smjc7t3):
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: "a"

Question 1 (Question id: q_oxFwpR):
How many times does the letter "d" appear in the text: "the United"? 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'.
Also add the answer type as 'string' or 'integer' to the field 'answer_type' for each object.
If the response to a question is an integer that is even, also add the field 'half_answer' to the object which contains the answer integer divided by two.

Now provide the result JSON using the described format.

{"ground_truth": {"q_Smjc7t3": {"answer": "a", "answer_type": "string"}, "q_oxFwpR": {"answer": 1, "answer_type": "integer"}}}
