Please HELP me!!!

1.     Below is an excerpt from a letter that was sent by the chairman of a corporation to the stockholders.

A number of charges have been raised against me, some serious, some trivial. Individuals seeking to control the corporation for their own purposes have demanded my resignation. Remember that no court of law in any state has found me guilty of any criminal offense whatsoever. In the American tradition, as you know, an individual is considered innocent until proven guilty. Furthermore, as the corporation’s unbroken six-year record of growth will show, my conduct of my official duties as chairman has only helped enhance the success of the corporation, and so benefited every stockholder.

Which of the following can be properly inferred from the excerpt?

(A) The chairman believes that all those who have demanded his resignation are motivated by desire to control the corporation for their own purposes.

(B) Any misdeeds that the chairman may have committed were motivated by his desire to enhance the success of the corporation.

(C) The chairman is innocent of any criminal offense.

(D) The corporation has expanded steadily over the past six years.（D）

(E) Any legal proceedings against the chairman have resulted in his acquittal.

(D) An increase in the number of bird species in and around a city is desirable.（A）

(E) The increased sightings of bird species in and around London reflect an actual increase in the number of species in the area.
