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_ckspatk):
Find the value of k in the equation: 19*k - 11 = 312 Respond with an integer.

Question 1 (Question id: q_X69UblO):
Determine the value of w that satisfies: 8*w - 13 = 147 Respond with an integer.

Question 2 (Question id: q_UXt38j):
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 woodlouses, 2 chickens, 3 crickets, 2 shrimps, 1 grasshopper?
 Respond with an integer.



Output JSON where all question ids are keys, omitting q_X69UblO.

For every question id, supply an object whose 'answer' field stores the solution.
For even integer answers, include 'half_answer' equal to answer ÷ 2.
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.

Now provide the result JSON using the described format.
