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_q2VA):
Solve for x: 20*x + 1 = 301 Respond with an integer.

Question 1 (Question id: q_jXrj):
How many times does the letter "a" appear in the text: "early as"? Respond with an integer.



Return a JSON with each question id as a key.

Each key’s value must be an object holding an 'answer' field.
For even integers, nest 'half_answer' and 'double_answer' inside an additional 'additional_answer_info' field in the answer object.
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.

Beyond the question-id fields, add a 'global_metadata' object with summary information:
'num_questions_asked' should equal the total questions that appeared.
'num_questions_answered' must hold the number of answered questions.
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_q2VA": {"answer": 15}, "q_jXrj": {"answer": 2, "additional_answer_info": {"half_answer": 1, "double_answer": 4}}, "global_metadata": {"num_questions_asked": 2, "num_questions_answered": 2, "questions_with_integer_answers": ["q_q2VA", "q_jXrj"]}}}
