Oppenheimer’s brief advance into astrophysics began with
a 1938 paper about neutron stars, which continued in a 1939
installment that further incorporated the principles of Einstein’s
general theory of relativity. He then published a third paper on
black holes on September 1st, 1939—but at the time, it was
scarcely noticed because this was the very day Germany invaded
Poland, launching World War II. Oppenheimer never wrote on
the topic again.
Even if it hadn’t been overshadowed by war,
Oppenheimer’s work on neutron stars and black holes “was not
understood to be terribly significant at the time,” says Cathryn
Carson, a historian of science at the University of California,
Berkeley.
Each paper was written with a different member of the
swarm of graduate students that Oppenheimer carefully
cultivated. These protégés facilitated his ability to jump between
research topics—and ultimately, helped him develop some of his
most important contributions to physics.
Oppenheimer’s climactic third paper, written with his
student Hartland Snyder, explores the implications of general
relativity on the universe’s most massive stars. Although the
physicists needed to include some assumptions to simplify the
question, they determined that a large enough star would
gravitationally collapse indefinitely—and within a finite amount
of time, meaning that the objects we now know as black holes
could exist.

Texto CB1A1-I
Os testes econométricos realizados para o estado de São
Paulo mostram que a disponibilidade de gás natural teve
importância na localização industrial. Tal resultado é corroborado
pela avaliação de que seu efeito impacta mais a indústria
consumidora intensiva do que a média das indústrias.
Por outro lado, esta análise também está limitada pelo
conjunto de variáveis disponíveis para controle. Embora tenham
sido incluídas no modelo variáveis fundamentais no processo de
localização, é inevitável que haja um grupo de variáveis omitidas.
Citam-se, por exemplo, a relação entre os preços dos energéticos,
as questões tributárias, a proximidade com pontos de exportação
e com outras fontes de insumos importantes.
Essa constatação, por sua vez, não diminui a relevância
dos testes produzidos. Ao contrário, se se pode provar que a
malha de gasodutos do país serve como fator de atração de
atividade econômica, pode-se apontar mais uma possibilidade de
atuação do setor público no intuito de garantir um processo de
desconcentração econômica mais efetiva no país. A construção
de uma malha mais eficiente e abrangente surge, portanto, como
um importante desafio a ser considerado no planejamento
energético nacional.
Edgar Antonio Perlotti et al. Concentração espacial da indústria de São Paulo:
evidências sobre o papel da disponibilidade de gás natural. Energia e ambiente.
30 (87), maio-ago./2016 (com adaptações).
Considerando as relações de concordância verbal estabelecidas no texto CB1A1-I, julgue o próximo item.
A forma verbal que inicia o último período do segundo parágrafo está na voz passiva pronominal e sua flexão na terceira pessoa do plural justifica-se pelo fato de o sujeito ser composto.

Estaria mantida a correção gramatical do texto caso a forma verbal “serve” (segundo período do último parágrafo) fosse flexionada na terceira pessoa do plural — servem —, dada a possibilidade de concordância verbal com o termo mais próximo, “gasodutos”.

No segundo período do segundo parágrafo, a supressão do segmento “um grupo de” ensejaria que a forma verbal “haja” fosse flexionada no plural — hajam —, para a adequada concordância com o termo “variáveis”.
