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_SGEsvOxF):
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"

Question 1 (Question id: q_fMMTK):
Calculate ( -2 * 7 ) * -5.

Question 2 (Question id: q_l67xZ):
Solve for q: 260*q - 480 = 560 Respond with an integer.

Question 3 (Question id: q_MkmG0):
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: "country"

Question 4 (Question id: q_KYcoSvYR):
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: "chemistry"

Question 5 (Question id: q_aKU9):
Calculate -1 - -4.

Question 6 (Question id: q_74Qb):
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: "sold"



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

For every question id, supply an object whose 'answer' field stores the solution.
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.
