The slow advancement of the technology used in golf balls is

[BTGmoderatorDC]

The slow advancement of the technology used in golf balls is a reflection of the demand which manufacturers aim to meet. Only goflers active in competition tournaments are willing to pay the high price necessary to justify the reserach and development costs needed to generate an innovative golf ball. Therefore, the technology that manufacturers pursue is limited to that which is deemed permissible for competition go tournaments.

The above conclusion rests upon which of the following assumptions ?

A. The slow pace of technological advancement is a consequence of golf ball manufacturers not wanting to manufacture different products for different national markets.
B. Unless the market for balls for competition golfers expands, the market for golf balls for non-competing golfers will not expand
C. Innovative golf balls are more likely to be developed by small, young manufacturing companies than by industry giants.
D. There is not a strong demand for non-competition permissible golf balls generated by competition golfers.
E. The authorities who determine what is permissible in competition gold tournaments are not necessarily up-to-date on cutting edge technological improvements.

To find out the assumption to which the conclusion rests upon, we must find out what could have prompted such a conclusion.
Premise: Slow advancement of the technology used in golf balls is a reflection of the demand which manufacturers aim to meet.
Explanation: The advancement of technology associated with the use of golf balls is quite slow due to its low demand. The only set of individuals interested in it are the golfers active in competitive tournaments.
Conclusion: The technology that manufacturers pursue is limited to that which is deemed permissible for competition go tournaments.

OPTION A - INCORRECT
This assumption is irrelevant to the conclusion given because the argument is not about the manufacturing of different products for different international markets.

OPTION B - INCORRECT
The conclusion's major concern is the advancement of technology in golf balls, not ordinarily for the market of balls.

OPTION C - INCORRECT
We don't care about who manufactures these balls. It doesn't explain the relationship between the technology being pursued in the argument and how it is connected to the golfer active in competitions.

OPTION D - CORRECT
This is true, the technology available is limited to what can be used for competition, and it rests on this assumption.

OPTION E - INCORRECT
This is outside the scope of the argument. The argument only deals with the advancement of the technology used in golf balls.
