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_Vwl38):
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_7t8O):
Calculate -4 * -7 + 1.

Question 2 (Question id: q_VUtLDjx):
How many times does the letter "8" appear in the text: "the year 2889"? Respond with an integer.

Question 3 (Question id: q_zozf):
How many times does the letter "h" appear in the text: "belligerents might"? Respond with an integer.



Create a JSON object keyed by every question id except q_7t8O.

For every question id, supply an object whose 'answer' field stores the solution.
Also add the answer type as 'string' or 'integer' to the field 'answer_type' for each object.
For even integer answers, include 'half_answer' equal to answer ÷ 2.
For string answers, include 'first_char' with the answer’s initial letter.

Beyond the question-id fields, add a 'global_metadata' object with summary information:
• num_questions_asked – total number of questions originally shown.

Now provide the result JSON using the described format.

{"ground_truth": {"q_VUtLDjx": {"answer": 2, "answer_type": "integer", "half_answer": 1}, "q_Vwl38": {"answer": "d", "answer_type": "string", "first_char": "d"}, "q_zozf": {"answer": 1, "answer_type": "integer"}, "global_metadata": {"num_questions_asked": 4}}}
