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_3Rjp3):
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 1 (Question id: q_8NAEjNh):
How many times does the letter "i" appear in the text: "laid down in"? Respond with an integer.

Question 2 (Question id: q_bfLvF3Z):
How many times does the letter "e" appear in the text: "the transformer And"? Respond with an integer.

Question 3 (Question id: q_NKdXvmPo):
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: "or"

Question 4 (Question id: q_M3Gn):
Determine the value of t that satisfies: 19*t + 9 = 218 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, add the field 'additional_answer_info' containing 'half_answer' (answer ÷ 2) and 'double_answer' (answer × 2).
If the response to a question is a string, add a 'first_char' field containing its first character.

Now provide the result JSON using the described format.
