[BlackCitadel]

Hello,
I finished my today's exam.
And I got a question which is requesting me to find the meaning of the following words:-

Mysteries:
Something like strange things that are legendary, I thought it's the same as Mysterious.

investors:
People who work in companies and plan for business.

impressed:
Delighted, surprised, or admired of something.

e-commerce:
A kind of (website) for selling (shopping) online. Because in the paragraph the word
e-commerce was written right before website
e-commerce website

Have you now looked for the definitions of those words in a dictionary?
