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_d1n2SpT):
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: "strength"

Question 1 (Question id: q_1MTnAVj):
Your task is to count how many legs there are in total when given a list of animals.

Now, how many legs are there in total if you have 2 jellyfishs, 3 cows, 1 shrimp, 2 giraffes, 4 flatworms?
 Respond with an integer.

Question 2 (Question id: q_tzqaMuvq):
Determine the value of j that satisfies: 8 - 5*j = 3 Respond with an integer.

Question 3 (Question id: q_9zAKSbWk):
Solve for d: 378*d = 7560 Respond with an integer.

Question 4 (Question id: q_7mpYe2t):
Your task is to count how many legs there are in total when given a list of animals.

Now, how many legs are there in total if you have 1 lion, 3 cats, 3 crickets?
 Respond with an integer.

Question 5 (Question id: q_iQg09o):
Calculate -7 * ( -7 - 0 ).



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

The value for each key should be an object that contains the answer in the field 'answer'.
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).
For string answers, include 'first_char' with the answer’s initial letter.
For last-character tasks, provide 'original_string' alongside the answer.

Now provide the result JSON using the described format.
