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_Xi8i):
Determine the value of o that satisfies: 2*o + 18 = 34 Respond with an integer.

Question 1 (Question id: q_9VpqM):
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 wasps, 4 shrimps, 2 butterflys, 2 tigers?
 Respond with an integer.

Question 2 (Question id: q_YAGl):
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: "they"

Question 3 (Question id: q_Sdc3k5sS):
Determine the value of d that satisfies: 18*d = 306 Respond with an integer.

Question 4 (Question id: q_tJiTg9e1):
Calculate 3 - -7 + 9.

Question 5 (Question id: q_T8C8):
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: "to"

Question 6 (Question id: q_r7egP):
Determine the value of v that satisfies: 9*v + 9 = 108 Respond with an integer.

Question 7 (Question id: q_U0GY6o0z):
How many times does the letter "r" appear in the text: "desired telephotic"? Respond with an integer.

Question 8 (Question id: q_99frJFIm):
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 sheep, 2 giraffes, 2 ducks, 3 snakes?
 Respond with an integer.



Create a JSON object keyed by every question id except q_U0GY6o0z.

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.

Now provide the result JSON using the described format.
