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_EJCZKfN):
Find the value of s in the equation: 5*s + 5 = 10 Respond with an integer.

Question 1 (Question id: q_kYCl9Dh):
How many times does the letter "r" appear in the text: "requests of"? Respond with an integer.

Question 2 (Question id: q_oMZwWe5Z):
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: "is"

Question 3 (Question id: q_39i7kby):
Calculate 2 / 2.

Question 4 (Question id: q_Z37ufoiO):
Calculate 8 * 2.



Output JSON where all question ids are keys, omitting q_kYCl9Dh, q_oMZwWe5Z.

For every question id, supply an object whose 'answer' field stores the solution.
Also add the answer type as 'string' or 'integer' to the field 'answer_type' for each object.
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.
