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_XojCd0):
Calculate -5 * 5 * -2.

Question 1 (Question id: q_nukUtdc):
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: "to"

Question 2 (Question id: q_bnVC):
How many times does the letter "e" appear in the text: "chemist and engaged"? Respond with an integer.

Question 3 (Question id: q_Mkf66if):
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 4 (Question id: q_nA9iDmQ9):
How many times does the letter "0" appear in the text: "000 000"? Respond with an integer.



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

Each key’s value must be an object holding an 'answer' field.
Include an 'answer_type' field (value 'string' or 'integer') for every answer object.
For even integer answers, include 'half_answer' equal to answer ÷ 2.
For string answers, include 'first_char' with the answer’s initial letter.
If the question asks for the last character of a string, add an 'original_string' field containing the source string.

Now provide the result JSON using the described format.
