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_HNScvJY):
How many times does the letter "v" appear in the text: "needs improvement remarked"? Respond with an integer.

Question 1 (Question id: q_70z3uz):
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 fireflys, 1 spider, 2 giraffes, 1 leech?
 Respond with an integer.



Return a JSON with each question id as a key.

For every question id, supply an object whose 'answer' field stores the solution.
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.
For string answers, include 'first_char' with the answer’s initial letter.
If the question asks for the last character of a string, add an 'original_string' field containing the source string.
When counting animal legs, include an 'animal_types' list of the distinct animal names (singular, sorted).

Now provide the result JSON using the described format.

{"ground_truth": {"q_HNScvJY": {"answer": 1}, "q_70z3uz": {"answer": 28, "half_answer": 14, "animal_types": ["firefly", "giraffe", "leech", "spider"]}}}
