IMO A

a) Sinusitis will be more common than either arthristis or high blood pressure in 2000.
(if the current trend continues more people will develop arthirstis and High BP as they grow old, and new people born will have sinusitis and people in all age group will also develop sinusitis so this has to be true)

b) Arthristis will be the most common chronic medical condition in 2000.
(there is no reason for this)

c) The average age of people suffering from sinusitis will increase between 1987 and 2000.
(logically it depends upon the birth rate and new occurences also)

d) Fewer people will duffer from sinustis in 2000 than suffered from it in 1987.
(there is no reason for this, new people born will have sinusitis)

e) A majority of population will suffer from at least one of the medical conditions mentioned above by the year 2000.
(this conclusio is also uncalled for)

A is going too far and out of the scope.

C is the only correct answer. Because who ever has Sinusitis will grow old with Sinusitis as the population gets older. Because people of all age will become older between 87-2000

I thought A was right the minute I read it but now I think C is most supported by the passage so I'll go with C.

The OA is C.

Here is the official explanation:

Given that the incidence rate for sinusitis is the same for people of all ages, and that the average age of population will increase, it follows that the average age of people suffering from sinusitis will increase. Therefore, C is the best answer.

Although it follow that sinusitis will become less common relative to arthritis and high blood pressure, nothing can be concluded about the exact ranking of the three diseases, so choice A and B are ruled out. Just because sinusitis will become relatively less common, one cannot conclude that it will become absolutely less common (choice D). Lacking information about levels of incidence of the diseases, one cannot conclude what porportion of the population has at least one of them. (choice E)

Can someone explain the bold line for me?

Dont agree with OA, what about new people born, if the birth rate increases, and as the question says any age group have possibility of sinus occurence, depending on how many newlyborn have sinus the average age of people with sinus might go down.

If C is the OA, the author did not think it thru very well...

I don't know. I have a tough time understanding the bold line above. This question is from Official Guide 10th Edition Critical Reasoning #174.

Any input is appreicated!!!

Dont understand your reasoning Ranga. C It looks obvious to me. If the average age of people increases, then the average age of people with Sinusitis will increase right? Average age census will take into account new births, deaths etc.

ranga, because the incidence rate of sinuitis doesn't occur more for any age group, it is not possible for more babies than adults to be born with the condition. Therefor, if the average age of the population increases, so to will the average age of those with sinuitis. At least that is how I see it.

The birth rate of babies can affect the final average....what if birthrate goes insanely high between 87 - 00, in that case more babies will have sinus (by proportion) and that might bring the average age of people with sinus down.....

People who do not understand my reasoning, please read it again....I know why C is obviously correct...but thinking futher it is not the correct answer...IMO

Ranga, I can understand your point, but if there is indeed a baby boom during that period, then the average age of the population will also come down. So, naturally, the average age of people with sinus will also come down.
Since the average age of population will increase, we can infer with a degree of confidence that there will be no baby boom between 1987 and 2000.
