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_vre1):
Determine the value of v that satisfies: 28*v = 420 Respond with an integer.

Question 1 (Question id: q_CpJ4W):
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: "fair"

Question 2 (Question id: q_4D1nPyZn):
Your task is to count how many legs there are in total when given a list of animals.

Now, how many legs are there in total if you have 2 horses, 4 crickets, 2 wasps, 4 giraffes?
 Respond with an integer.



Output JSON where all question ids are keys, omitting q_CpJ4W.

For every question id, supply an object whose 'answer' field stores the solution.
For even integer answers, include 'half_answer' equal to answer ÷ 2.
If the response to a question is a string, add a 'first_char' field containing its first character.

Beyond the question-id fields, add a 'global_metadata' object with summary information:
• num_questions_asked: how many questions were asked in total.
• questions_with_integer_answers: ids of questions with integer replies.

Insert 'combined_results', which should hold:
  • integer_info: maps each id to its integer answer
  • sum_of_answers: the combined total

Now provide the result JSON using the described format.

{"ground_truth": {"q_4D1nPyZn": {"answer": 60, "half_answer": 30}, "q_vre1": {"answer": 15}, "global_metadata": {"num_questions_asked": 3, "questions_with_integer_answers": ["q_4D1nPyZn", "q_vre1"]}, "combined_results": {"integer_info": {"q_4D1nPyZn": 60, "q_vre1": 15}, "sum_of_answers": 75}}}
