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_WRQOGFVk):
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: "the"

Question 1 (Question id: q_wlj3Z):
Determine the value of o that satisfies: 2*o + 18 = 34 Respond with an integer.

Question 2 (Question id: q_QkpmLeH):
Find the value of x in the equation: 60*x - 220 = 860 Respond with an integer.

Question 3 (Question id: q_VihfG8):
How many times does the letter "o" appear in the text: "donations to the"? Respond with an integer.

Question 4 (Question id: q_hM21Y):
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: "in"



Produce a JSON object whose top-level keys are the question ids.

For every question id, supply an object whose 'answer' field stores the solution. If a question involves animal-leg or letter counting, include 'task_type' set to 'leg_counting' or 'letter_counting'.
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.
For string answers, include 'first_char' with the answer’s initial letter.

Now provide the result JSON using the described format.
