(UERJ) What’s in a name?
The trouble with lingo
Remember the campaign in New York for garbage collectors to be called sanitation engineers?
Near the top of the strike’s agenda was the matter of getting the respect due to the people doing such essential work. Unfortunately, the new euphemistic title clarified nothing about the work and by now is either simply not heard for what it means, or is used in moments of gentle disdain. 10A clearer term may have both generated the respect desired and withstood the test of time.
Clarity and sincerity matter. Terms which mislead, confuse or cause offence can become a distraction from the real content of public debate. In the search for consensus, 2since public understanding is harder to change than terminology, changing the terminology might be a better place to start. No additional prejudice or emotion should be brought to a debate by the terminology used in it. Here are two examples.
Genetic Engineering and Genetic Modification
Despite the insistence of biotech scientists that genes of completely different species are no longer being mixed, the message isn’t being heard. They insist that they are now involved only in developments which simply hasten the natural processes of selective and cross breeding or cross pollination. As farmers and horticulturists have been doing exactly this, unquestioned, for years, they cannot understand public resistance.
The problem may well be the terminology. In this context, the words “scientific” or “genetic” have been irreparably sullied. If “genetic engineering” has, in the public’s view, become synonymous with the indiscriminate mixing of genes, and if the softer label “genetically modified” hasn’t been able to shake off a perception of sinister overtones, these terms might as well be dropped – or left attached only to experiments in Dr. Frankenstein’s laboratory.
Ideally, a new agricultural term would leave out the word “genetic” altogether: it seems to frighten the public. Assuming it described science’s benign genetic activities accurately, 8the term “productivity breeding” is not a trivial call for a euphemism; besides, it would probably encounter less public opposition.
So, let’s have new terms for selective cross breeding by scientists who simply speed up the same process that is carried out in nature.
Clean coal*
3If this new term was intended to be clear, it hasn’t worked.
In “Politics and the English Language” (1946), George Orwell wrote that 4because so much political speech involves defending the indefensible, 11it has to consist largely of euphemism. 6He insisted that, in politics, 7these euphemisms are “swindles” and “perversions” left deliberately vague in order to mislead. Deliberate or not, 12“clean coal” is one of these. Aside from being a contradiction in terms, the name is misleading, creating the impression of the existence of a new type of coal. In fact, it is 13ordinary coal which has been treated to “eliminate” most of its destructive by-products, which are then buried. The whole process produces emissions. 5This, though, isn’t clear when it is simply labelled “clean coal”. The term just doesn’t seem sincere. 9It’s a red rag to any green. It’s not asking too much to expect the term describing these procedures to be more accurate. A clearer term would be less provocative.
1So, what’s in a name? A lot. There’s the possibility of confusion, prejudice, perversions and swindles. For the sake of fair debate, let’s mean what we say and say what we mean.
* Coal: carvão

(FUVEST 2008 1ª FASE) “No Chile, a lei não serve para outra coisa a não ser produzir a anarquia e a ausência de sanções [...] Se eu, por exemplo, prendo um indivíduo que sei que está tramando uma conspiração [contra o governo], violo a lei. Maldita lei então que não deixa o braço do governo proceder livremente no momento oportuno. [...] De minha parte, sei dizer que, com lei ou sem ela, essa senhora que chamam de Constituição tem que ser violada quando as circunstâncias são extremas.”
Carta de Diego Portales, ministro chileno, em 1834.

(UECE) Os cogumelos são estruturas importantes para a reprodução de determinados tipos de fungos e apresentam uma morfologia muito particular que permite a identificação taxonômica dos mesmos. O Shimeji é um dos cogumelos mais difundidos no mundo. Assim como o Shiitake (Lentinula edodes), o Shimeji (Pleorotus) é muito consumido na Ásia, principalmente na China, sendo também muito utilizado na preparação de pratos japoneses. Já o Cogumelo do Sol (Agaricus blazei) vem sendo muito consumido por suas propriedades medicinais.

Considere os exemplos de características anatômicas e fisiológicas de três seres vivos.
- O chimpanzé (Pan troglodytes) possui visão binocular e o primeiro dedo oponível nas mãos. A visão binocular permite que o cérebro distinga as diferentes distâncias entre os objetos observados e o observador e a presença do primeiro dedo oponível nas mãos permite o movimento de pinça, facilitando agarrar objetos.
- O inseto maria-fedida (Nezara viridula) libera um odor, produzido por glândulas toda vez que se sente ameaçado. Além dessa defesa, ele pode apresentar algumas colorações, como verde ou marrom, o que auxilia na proteção contra predadores.
- A planta urtiga (Urera baccifera) apresenta tricomas urticantes na superfície de suas folhas. Eles secretam substâncias ácidas, causando vermelhidão, coceira e ardência na pele de uma pessoa que as toca.
Esses três seres vivos apresentam
