Study the following information carefully and answer the questions given below:
In a certain code language:
“Summer season is boring” is coded as “mn hn rd hi”
“Winter season are gone” is coded as “jk hn tr vb”
“People feel boring summer” is coded as “mn rd bx az”
“boring feel are gone” is coded as “rd jk vb az”

What is the code of “is” as per the given code language?

To find the code for the word "is", we can analyze the given code language by comparing the sentences and their respective codes:

1. "Summer season is boring" is coded as "mn hn rd hi"
2. "Winter season are gone" is coded as "jk hn tr vb"
3. "People feel boring summer" is coded as "mn rd bx az"
4. "boring feel are gone" is coded as "rd jk vb az"

Let's find the codes for the words in the first sentence to isolate the code for "is":

- Compare Sentence 1 ("Summer season is boring") and Sentence 2 ("Winter season are gone"):
The common word is "season", and the common code is "hn". Thus, the code for "season" is "hn".

- Compare Sentence 1 ("Summer season is boring") and Sentence 3 ("People feel boring summer"):
The common words are "summer" and "boring", and the common codes are "mn" and "rd".

- Compare Sentence 3 ("People feel boring summer") and Sentence 4 ("boring feel are gone"):
The common word is "boring", and the common code between them (which is also in Sentence 1) is "rd". Thus, the code for "boring" is "rd".
Since "summer" and "boring" had the codes "mn" and "rd", and "boring" is "rd", the code for "summer" must be "mn".

Now we look back at Sentence 1: "Summer season is boring" is coded as "mn hn rd hi".
We have identified the following codes:
- "summer" = "mn"
- "season" = "hn"
- "boring" = "rd"

The only remaining word in the sentence is "is", and the only remaining code is "hi".

Therefore, the code for "is" is "hi".
