Post again, bit this time ask what exactly you're being asked to do.
Does that say to write a story of a world-dominating squirrel? Conflict statement....
Well I would assume that this means somebody is reading another person's face so that they can memorize their features?
Pets are reliable friends to owners needing companionship. Doctors need to consider that a pet is most likely to lower blood pressure and stress in a patient. Pets need to suffer from lack of attention and shelters can provide homes by partnering with those that use a pet.
The correct answer is D, this is 'present perfect' tense. It is formed with the use of the verb HAVE in present simple tense (so, HAVE/HAS), and the past participle of a verb (or the third column of irregular verbs).
A cannot be correct, because then it would say - I hear.
B cannot be correct, because then it would say - I had heard.
C cannot be correct, because then it would say - I heard.
And since there is also HAVE HEARD, the correct answer has to be D.
