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_ri2MEC):
How many times does the letter "r" appear in the text: "of this electronic"? Respond with an integer.

Question 1 (Question id: q_HDat8S):
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 grasshopper, 1 praying mantis, 3 sheeps, 1 crab, 4 woodlouses?
 Respond with an integer.



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'.
If the response to a question is an integer that is even, also add the field 'half_answer' to the object which contains the answer integer divided by two.
If the response to a question is a string, add a 'first_char' field containing its first character.
For last-character tasks, provide 'original_string' alongside the answer.

Now provide the result JSON using the described format.

{"ground_truth": {"q_ri2MEC": {"answer": 1}, "q_HDat8S": {"answer": 90, "half_answer": 45}}}
