A powder derived from the North American Echinacea flower, which has b...

To answer this question, you first have to realize that the basic structure of this sentence is fairly simple. The main verb of the sentence is “grown”. What is grown? A flower is grown, not its derivative. Choices A, B, C and D all imply that it is a derivative or a powder which is grown out West and not the flower. This is a clear flaw in logic. The only answer choice that has the correct subject is Choice E.

Evaluating the options:

a) "A powder derived from the North American Echinacea flower, which has been effective in preventing colds": This option is grammatically correct and conveys the intended meaning. However, it is quite wordy and can be improved for clarity and conciseness.

b) "A derivative, which has been effective in preventing colds, of the North American Echinacea flower": This option is also grammatically correct, but the use of the term "derivative" may not be as clear as using "powder" or "product." Additionally, the phrase "of the North American Echinacea flower" seems misplaced.

c) "A North American Echinacea flower derivative, which has been effective in preventing colds": This option is grammatically correct and concise. It effectively conveys the information that the powder is derived from the North American Echinacea flower and has been effective in preventing colds.

d) "The North American Echinacea flower has a derivative which has been effective in preventing colds, that": This option is grammatically incorrect. The use of "that" at the end of the sentence is unnecessary and creates a fragment.

e) "The North American Echinacea flower, a derivative of which has been effective in preventing colds": This option is grammatically correct and concise. It effectively conveys the information that the North American Echinacea flower is the source of the derivative, which has been effective in preventing colds.

Choosing the correct option:
Option (e) is the best choice as it is grammatically correct, concise, and effectively conveys the intended meaning. It clearly states that the North American Echinacea flower is the source of the derivative, which has been effective in preventing colds.

By evaluating the options based on grammar, clarity, conciseness, and the ability to convey the intended meaning, we can determine that option (e) is the most suitable choice.

What is grown???
the flower not derivative .this is the clue.
except E all are violation of modifier and in D it's a meaning error it says flower has a derivative and that present after comma is a run on sentence error.

Read the passage and answer the question given below.American companies may find the solution to their performance related problems in their own backyard. A recently conducted independent study shows that in the business world, social and political skills have become the real key to getting ahead in organisations, skills that successful managers use to their advantage. The study found out that successful managers, those who get promoted relatively quickly vis-à-vis effective managers, perform day to day activities that are more or less dissimilar to the ones conducted by effective managers or those who have satisfied, committed subordinates, in addition to high performing units. Accordingly, it comes as no surprise that networking, which consists of socializing or politicking and interacting with others, was one activity that, out of the core four activities among the plethora of activities performed by managers, topped the list for successful managers but was ranked the lowest in the list of activities performed by the effective ones. Indeed the findings of the study do not negate the reality that there are managers who strike a balance between the activities performed by both types of managers and hence are successful and effective at the same time, but the meagre percentage such managers formed of the study’s sample, barely ten percent, affirms the general divide between successful and effective managers.These findings clearly belie the traditional assumption typically suggested by formal personnel policies that promotions are based purely on performance. In effect, the study’s implications affirm the cynical, yet what now seems real, view that people who are not necessarily the most accomplishing in terms of performing well in the other three key activity areas, namely communication, traditional management, and human resource management, are being promoted to the top level. Therefore, American companies looking to improve their performance and productivity need to ensure that formal rewards, especially promotions, are tied to performance. This way companies will be promoting a work-culture that turns effective managers in to successful managers and gives the currently successful managers a chance to effectively focus on productivity and not just on socializing and politicking.Q. Which of the following is mentioned in the passage?

Recent research shows that training programs that include emphases on flexibility, highlighting activities such as yoga and pilates, are significantly more effective at preventing injury in athletes than are training programs that solely focus on strength and speed. The Bournemouth Football Club suffered fewer injuries than the Haleford Football Club this past season, so it can be concluded that Bournemouths training program featured more flexibility activities than did the program at Haleford.The argument is most vulnerable to criticism because it
