Should be struck -> morally obligated to be struck. An awkward meaning and thus we can eliminate options A, B, and E.

(C) a meteorite will strike one human being once in every nine years. "a human being" is a better expression. Moreover, the sentence implies that all the meteorites in the sky will find a person to strike. That's surely not the intended meaning .
(D) every nine years a human being will be struck by a meteorite

Thus option D.

Canadian scientists have calculated that one human being should be struck every nine years by a meteorite, while each year 16 buildings can be expected to sustain damage from such objects.

(C) a meteorite will strike one human being once in every nine years
(D) every nine years a human being will be struck by a meteorite

I looked for parallelism and found D better

It is doubtful whether 'will' always means a certainty. For example, take this case:
Seeing the binge with which Yellen is eager to go, analysts think that FED will raise the rate yet again as early as March this year.

Here, 'will' signifies more speculation or at the most some anticipation or expectation. 'Will' is often used for the futurity of the event rather than for the surety of the event.

The next point. 'Should' is often a kind of suggestion and in some cases even dreaming. For example. I think he should re-take GMAT again ASAP. Here this is a mere suggestion.
In another case, --- I feel that the erring politician should meet his waterloo this time for hobnobbing with anti-socials. -- here this is a wishful thinking.
Therefore, 'should' may not always point to compulsion as in the case of 'ought to' or 'must'

Canadian scientists have calculated that one human being should be struck every nine years by a meteorite, while each year 16 buildings can be expected to sustain damage from such objects.

(A) one human being should be struck every nine years by a meteorite
(B) a human being should be struck by a meteorite once in every nine years
(C) a meteorite will strike one human being once in every nine years
(D) every nine years a human being will be struck by a meteorite
(E) every nine years a human being should be struck by a meteorite
let's drop A and C for using the unseemly One human being suggesting somewhat oddly that one same human being is struck by a meteorite every nine years once. Let's us eliminate B and E for the wrongful suggestion by using the inapt 'should. D remains

(A) one human being should be struck every nine years by a meteorite
(B) a human being should be struck by a meteorite once in every nine years
(C) a meteorite will strike one human being once in every nine years
(D) every nine years a human being will be struck by a meteorite correct
(E) every nine years a human being should be struck by a meteorite

In A and C, it seems we are talking about a particular human being.
Wrong meaning in B.

the use of "will" is basic and easy but we need to review grammar books to understand this use properly.

"will " can be used to show a future action
I will learn gmat tomorow.

"will" can work as model verb (verb must used with another verb, like can, may, must) to show possibility, intention, habit and decision
I think that a person will be struck by a meterorite.
"should" can be used only as advise/obligation.

you do not need to read grammar book now. that is all for will and should.

gmat test basic and hard grammar point. grammar points is never hard because it is just rules. but we need to understand the rules properly.

A. one human being should be struck - strange meaning....it seems the person should be struck..mandate..
B. one human being should be struck - strange meaning....it seems the person should be struck..mandate..
C. the second clause starts with while each year.....the first one should have time frame as the first phrase....
D. seems ok....every nine years.....while each year......parallel.
E. should be struck gives a different meaning.....

Hi RonPurewal

Could I please request a clarification?

- Can "should" be used to convey probability?
- Can "will" be used to convey probability? Or, in this context "will" is used to convey certainty?

What does, in fact, separate D from E?

(D) every nine years a human being will be struck by a meteorite

should is used to show advice.
will is used to show
1 . a future action. i will learn gmat tomorow
2. a certainty. he will come here now
3. a willingness. i will give you a job
4. a habit.

so, will can be a future action or can be a model verb showing: certainty, willingness and habit.

back our problem, scientist talk about a certainty. so, will is good.

Hello TheRzS,

Since you have a couple of doubts, I would just like to add my two cents here.

Quote:
- Can "should" be used to convey probability?

The answer is no. The word should is used to present obligation.

Quote:
- Can "will" be used to convey probability? Or, in this context "will" is used to convey certainty?

It is true that the helping verb will is generally used to present an action that is going to happen for sure. However, verb tenses are the trickiest part of the grammar. Their correct usage is completely governed by the context of the sentence.

Per the context of the sentence, it is easy to understand that the author wants to present probability. It is not that we see humans getting hit by a meteor as general occurrence. So yes, per the context of this official sentence, usage of will basically shows a calculation.

Now let's talk about the difference between Choices D and E.

(D) every nine years a human being will be struck by a meteorite: Correct: As explained, will has been used to present a calculation.

(E) every nine years a human being should be struck by a meteorite: Incorrect: Usage of should suggests that a person must for sure be struck by a meteorite as if it is the duty/obligation of a man to be struck by a meteorite.

Hope this helps.
Thanks.
