Hi. i have completed the following excercises. I would like some help in checking them please.

  1. The health is the most important thing in the life.

I believe the error is the use of “the”. A definite article has been incorrectly used. The word ‘the’ is used to refer to specific nouns. Health is not a specific noun.

  1. My mother is lawyer.

The learner has failed to use an indefinite article in the sentence. The article “a” shoud have been used after the word "is’.

  1. My family living in Iran.

The word should be live
