Summary
A design that turns out well has usually gone through many drafts, with each improving on the last. Sketching an idea usually allows a designer to see an idea’s flaws and advantages. Areas where the sketch feels confused reveals where the design has been inadequately conceptualized.
Strongly Supported Conclusions
A design that turns out well has usually involved the designer sketching the design many times to see areas where the sketch has been inadequately conceptualized.
A
The designs that turn out best go through the most drafts.
This is unsupported because we don’t have enough information to state the superlative that the drafts that turn out best go through the most drafts. We only know that good designs in general typically have many drafts.
B
Many good designs have emerged from design ideas that were flawed.
This is strongly supported because if good designs are the products of drafting an idea many times, and drafts are useful because they help a designer see where a sketch is flawed, many of those good ideas had initial flaws that were improved on subsequent drafts.
C
Designs that do not turn out well have not gone through many drafts.
This is unsupported because many drafts is usually necessary for good designs, not sufficient as this answer choice sees it.
D
Designs whose initial conceptualization was inadequate rarely turn out well.
This is unsupported because the initial conceptualization may be able to be refined over a series of many drafts even if the initial conceptualization was inadequate.
E
A designer will never see advantages and flaws in a design idea without the aid of a sketch.
This is unsupported because while a sketch helps designers see flaws, it is too strong to say that sketches are a necessary condition of seeing flaws as answer choice E implies.
