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_v19g):
Solve for o: 17*o - 2 = 15 Respond with an integer.

Question 1 (Question id: q_1vw6Q):
How many times does the letter "f" appear in the text: "that if"? Respond with an integer.

Question 2 (Question id: q_pzpSX):
How many times does the letter "t" appear in the text: "ago its"? Respond with an integer.

Question 3 (Question id: q_3hJ4):
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 4 lions, 2 praying mantiss, 4 shrimps, 3 cows?
 Respond with an integer.

Question 4 (Question id: q_lhkbC):
How many times does the letter "y" appear in the text: "copyright notice"? Respond with an integer.



Return a JSON with each question id (except for q_v19g, q_1vw6Q) 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.
If the response to a question is a string, add a 'first_char' field containing its first character.

Now provide the result JSON using the described format.
