Choice A: This answer choice displays subject-verb disagreement between "duration" and "are". Thus, this answer choice is incorrect.
Choice B: This answer choice uses the present continuous tense to refer to a habitual action; to believe in something is not a an ongoing action, it is a habit. Thus, this answer choice is incorrect.
Choice C: This answer choice uses the unidiomatic phrase "termed to be"; the word "termed" follows the same idiomatic constructions as "considered". Thus, this answer choice is incorrect.
Choice D: This answer choice maintains proper tense use, idiomatic construction, and subject-verb agreement throughout the sentence. Thus, this answer choice is correct.
Choice E: This answer choice fails to pair the word "neither" with the word "nor", leading to an unidiomatic construction. Thus, this answer choice is incorrect.
Hence, D is the best answer choice.To understand the concept of "Simple Tenses on GMAT", you may want to watch the following video (~1 minute):
