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_GJLLyX):
Calculate ( ( ( -4 + 8 ) ) ).

Question 1 (Question id: q_RS1LX5ex):

Solve for r: 30 - 4*r = -10 Respond with an integer.

Question 3 (Question id: q_Vg0y):
Find the value of i in the equation: 20*i + 7 = 187 Respond with an integer.

Question 4 (Question id: q_pwkY6lpv):
Calculate ( ( -3 - -7 ) ) - -6.

Question 5 (Question id: q_JA3kwE):
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: "it"

Question 9 (Question id: q_AqPNV):
How many times does the letter "s" appear in the text: "to the works"? Respond with an integer.

Question 10 (Question id: q_BTrw):
Calculate 4 * 3.

Question 11 (Question id: q_v0Lc):
How many times does the letter "e" appear in the text: "the summer"? Respond with an integer.



Your output must be a JSON mapping every question id to its answer info.

Each key’s value must be an object holding an 'answer' field.
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 last-character tasks, provide 'original_string' alongside the answer.

Now provide the result JSON using the described format.
