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_LUhetO):
Calculate -5 + 7.

Question 1 (Question id: q_Xpjdo7Xc):
Determine the value of w that satisfies: 18*w + 12 = 66 Respond with an integer.

Question 2 (Question id: q_eFUYxXpC):
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 cows, 4 insects, 3 horses, 1 human, 3 sheeps?
 Respond with an integer.

Question 3 (Question id: q_vAAVzTH):
Find the value of k in the equation: k = 1 Respond with an integer.

Question 4 (Question id: q_LaO5):
Calculate ( 5 * 2 ).

Question 5 (Question id: q_R98itl):
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 3 grasshoppers, 2 beetles, 2 jellyfishs, 2 flatworms, 2 dogs?
 Respond with an integer.

Question 6 (Question id: q_C1jr8V6):
Calculate 5 - 5 - -9.

Question 7 (Question id: q_yoFiOgA):
Your job is to return the last character of a string as a string. For example, the last char of "hello" is "o". Return the last character of the following string: "been"



Output JSON where all question ids are keys, omitting q_LUhetO, q_eFUYxXpC, q_vAAVzTH.

Each key’s value must be an object holding an 'answer' field.
If the response to a question is an integer that is even, add the field 'additional_answer_info' containing 'half_answer' (answer ÷ 2) and 'double_answer' (answer × 2).
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.
