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_lje7sP):
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 giraffes, 1 grasshopper, 4 butterflys, 2 cows?
 Respond with an integer.

Question 1 (Question id: q_I8rMm):
How many times does the letter "t" appear in the text: "extension chair"? Respond with an integer.

Question 2 (Question id: q_wSRiEI):
Find the value of m in the equation: 9*m + 11 = 20 Respond with an integer.

Question 3 (Question id: q_J8lfmB6):
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: "and"



Return a JSON with each question id (except for q_lje7sP) as a key.

Each key’s value must be an object holding an 'answer' field. Additionally, if the task is about counting legs of animals or counting letters in a string, add the task_type field with value 'leg_counting' or 'letter_counting', respectively.
For even integer answers, include 'half_answer' equal to answer ÷ 2.

Now provide the result JSON using the described format.
