Thank you for using the timer!
We noticed you are actually not timing your practice. Click the START button first next time you use the timer.
There are many benefits to timing your practice, including:
as might imply while/because-- not correct here Than is wrong because there is no comparative word form used here- like more or less or greater If you use of what - the construction becomes- three times the price of what X charges..Here what stands for price..so, it seems to imply-three times the price of the price..that makes it wrong And finally, 'charges at' is wrong idiom- you can say he sells at a price of.. but you cant say he charges at a price..simply, charges the price. Charges doesnt take at, therefore at which is wrong. Left with D.
to see the struction more clearly, you can eliminate "per miligram" to see: A is being sold for 3 times the price as Mr.Drug charges for B with the same active ingredient. If you replace "of what" in (D), the sentence is totally absurb: "the price of what", do you see it awkward?
Consider giving me kudos if you find my explanations helpful so i can learn how to express ideas to people more understandable.
A new hair-growth drug is being sold for three times the price, per milligram, as the drug's maker charges for another product with the same active ingredient.
A) B) than C) that D) of what E) at which
Its C. price should be object of the charges... E.g the game that we played..(game object of played) the table that I bought (table object of bought) Similarly. the price that maker charges (price object of charges)
Metallicafan, the category that this falls into is comparison, but the skill necessary to identify the correct structure for that comparison is the skill exhibited by the above posters-- identifying which modifiers are used to clutter the sentence's structure, and ignoring those superfluous chunks to see the underlying grammar. The prep companies worth their salt have content work with comparisons and modifiers built into their curricula, and teach you how to identify those underlying structures.
An exercise I sometimes give to my students who struggle with this concept is to take any sentence and boil it down to its essential core--you can do this with newspaper articles, OG questions, or anything else densely written.
