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_la8PIK):
Find the value of h in the equation: 20*h + 15 = 215 Respond with an integer.

Question 1 (Question id: q_DJXi):
How many times does the letter "t" appear in the text: "of optics is"? Respond with an integer.

Question 2 (Question id: q_CyrS6cB):
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 1 sheep, 3 crabs, 3 flatworms?
 Respond with an integer.

Question 3 (Question id: q_n9FBgkkE):
How many times does the letter "i" appear in the text: "In two"? Respond with an integer.

Question 4 (Question id: q_YIZCtMBI):
Calculate 4 - -5.



Your output must be a JSON mapping every question id to its answer info.

The value for each key should be an object that contains the answer in the field 'answer'.
For even integers, nest 'half_answer' and 'double_answer' inside an additional 'additional_answer_info' field in the answer object.
For last-character tasks, provide 'original_string' alongside the answer.

Beyond the question-id fields, add a 'global_metadata' object with summary information:
Include 'num_questions_asked' to record the total number of questions presented.

Now provide the result JSON using the described format.
