For parallelism, 17 commercials should come at the end
Between B and C, pick C. 'should be' suggests 'not definite' and this is parallel to 'can be expected to' in the non-underlined part of the passage

I don't know why, but am inclined to choose (A).

1. I guess that 'during' is better than 'in'.
2. I guess that 'should' is better than 'will'.

I know ywilfred and laxieqv are almost always right, and so I'm very suspicious of my own answer.

OA is B.

OE (From Kaplan GMAT800)

The main grammatical problem in the sentence as it originally stands is should be shown. Looking at the rest of the sentence, you can see that should be shown contrasts with can be expected to contain. Should is wrong because it indicates that the number of commercials per sitcom is hypothetical; it needs to be changed to will be shown or an equally declarative construction in order for the sentence to be grammatically correct. Only choices B and E make that correction. Eliminate E for changing during a half hour sitcom to by a half hour sitcom. The alteration changes the meaning of the original sentence and makes no sense in its own right: the sitcom can`t show commercials. B remains.

I have points here that I'm not too clear about. I think both of us agree that 'should' is hypothetical. But I think 'can be expected' is also hypothetical. For instance "Rain is expected to fall tomorrow" doesn't mean rain will fall but very likely. So in a way, the forecast is hypothetical, isnit it?

ywilfred> In my experience there are different levels of expressing probability in English by using harder vs. softer modals.
Hypothethical expressions vary in meaning, from the somewhat improbable (softer) "could" to the most probable (harder) "will." "Can" is slightly higher in possibility than "could,"whereas "might," "maybe," "should," "probably," " and "most likely" fall in between, respectively.

As for the chance of rain tommorrow, you might want use this sequence as a rough guide:

can`t-->won`t-->highly improbable-->improbable-->possible-->could-->can-->might-->may(maybe)-->should-->probably-->most likely-->definately-->must-->will-->absolutely will
