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_RWhTbh3):
Determine the value of u that satisfies: 134 - 20*u = 94 Respond with an integer.

Question 1 (Question id: q_fyJ0OlFX):
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 dogs, 2 leechs, 2 fireflys, 2 spiders, 1 insect?
 Respond with an integer.

Question 2 (Question id: q_qUFLcJFQ):
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: "some"



Return a JSON with each question id (except for q_RWhTbh3) as a key.

Each key’s value must be an object holding an 'answer' field.
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.
If the question asks for the last character of a string, add an 'original_string' field containing the source string.

Add a top-level 'global_metadata' field that records overall stats:
'num_questions_asked' should equal the total questions that appeared.
Fill 'questions_with_integer_answers' with the ids of integer-answer questions (leave empty when none).

Now provide the result JSON using the described format.

{"ground_truth": {"q_fyJ0OlFX": {"answer": 42, "half_answer": 21}, "q_qUFLcJFQ": {"answer": "e", "first_char": "e", "original_string": "some"}, "global_metadata": {"num_questions_asked": 3, "questions_with_integer_answers": ["q_fyJ0OlFX"]}}}
