Challenge: Use the strong Tag to Make Text Bold

Link to the challenge:

You gotta read the instructions carefully. Make sure the period is outside the <strong> tag.

machines are stupid
if you are tasked to write Hello and you write Hello! you may think it is correct, but machines are stupid, so they think it is wrong
careful with these small things

I have same issue. I am stuck in this challenge.
In the code,I did not include the period. still, the error is " The strong tag should wrap around the words “Stanford University”."
Could you please explain this more?

are you sure you put only those words in there? other characters will make the test fail

Thank you. I fixed it. .
