Q5 to Q7:

       In American Genesis, which covers

            the century of technological innovation

            in the United States beginning in 1876,

Line     Thomas Hughes assigns special promi-

  (5)      nence to Thomas Edison as archetype

of the independent nineteenth-century

inventor.  However, Hughes virtually

ignores Edison’s famous contem-

porary and notorious adversary in

 (10)     the field of electric light and power,

George Westinghouse.  This com-

parative neglect of Westinghouse is

consistent with other recent historians’

works, although it marks an intriguing

 (15)     departure from the prevailing view

during the inventors’ lifetimes (and for

decades afterward) of Edison and

Westinghouse as the two “pioneer

innovators” of the electrical industry.

 (20)          My recent reevaluation of Westing-

            house, facilitated by materials found

            in railroad archives, suggests that

while Westinghouse and Edison shared

important traits as inventors, they

 (25)     differed markedly in their approach to

the business aspects of innovation.

For Edison as an inventor, novelty

was always paramount:  the overriding

goal of the business of innovation was

 (30)     simply to generate funding for new

inventions.  Edison therefore undertook

just enough sales, product development,

            and manufacturing to accomplish this.

Westinghouse, however, shared the

 (35)     attitudes of the railroads and other

industries for whom he developed

innovations:  product development,

standardization, system, and order

were top priorities.  Westinghouse

 (40)     thus better exemplifies the systematic

approach to technological development

that would become a hallmark of modern

corporate research and development.

Q7:

The author of the passage implies that the shift away from the views of Westinghouse’s contemporaries should be regarded as

1. a natural outgrowth of the recent revival of interest in Edison
2. a result of scholarship based on previously unknown documents
3. reflective of modern neglect of the views of previous generations
4. inevitable, given the changing trends in historical interpretations
5. surprising, given the stature that Westinghouse once had
