Tsunami waves!

[poonamchiK]

Often incorrectly referred to as a tidal wave, a tsunami, a seismic sea wave that can reach up to 150 miles per hour in speed and 200 feet high, is caused by underwater earthquakes or volcanic eruptions.

(A) up to 150 miles per hour in speed and 200 feet high, is

(B) up to 150 miles per hour in speed and heights of up to 200 feet, is

(C) speeds of up to 150 miles per hour and 200 feet high, are

(D) speeds of up to 150 miles per hour and heights of up to 200 feet, is

(E) speeds of up to 150 miles per hour and as high as 200 feet, are

OA is d. Bt i chose a. I am unable to understand why?

Pls help to explain.
Appreciate!

is this actually an official problem? there are very, very few hits for it on the web (most genuine official problems have lots and lots of web hits).

the easiest way to solve this problem is simply to use parallelism; the only choice in which the two statistics are written in the same way is choice (d). [edit: this was written incorrectly as (b) before; i meant (d)]

Hi there Ron,
thx for the reply. Yes its actually a problem i have encountered in the GMAT prep. What i am unable to understand is that in the correct answer - it says - "speeds of upto..."
Im not sure if i have ever heard anything like speeds and heights. Can you pls help explain?

Why would you say b is correct? I am just trying to understand this. I can't make out the ll-ism in upto 150 miles ... and heights of upto 200 miles.
I thought it should be upto 150 miles/hr in speed and upto 200 ft. in height.

I always find your post quite helpful and it has helped me build onto my idiom concepts.
Thx in advance.

poonamchik, I am certain that Ron meant to say that D is the only answer choice that is parallel. Sorry for the confusion.

[poonamchiK]

Forgive my questioning again. But what i really cant understand is that, is there such a thing as speeds?
Thats why i am unable to connect with D.

thx a ton.

Yes, you can use the word "speeds". For example, "My new car can attain speeds of up to 120 miles per hour".

And why A is wrong?

And why A is wrong?

like the other incorrect choices, it is clearly inferior to choice (d) in terms of parallelism.
