Cristina, Miguel, Patrícia e Antônio combinaram um encontro às 13 horas para assistir a uma apresentação de ginástica artística. Porém, eles não sincronizaram seus relógios, sendo que todos virão separadamente uns dos outros. Sabe-se que: • O relógio de Cristina está oito minutos adiantado em relação ao de Antônio; • O de Antônio está dois minutos atrasado em relação ao de Miguel; e • O de Patrícia está sete minutos adiantado em relação ao de Miguel. Se todos devem chegar exatamente às 13 horas, com base no horário de seus respectivos relógios, então

Nos Jogos Olímpicos Rio 2016, uma das grandes surpresas do Brasil foi a medalha de ouro (primeiro lugar) no salto com vara de Thiago Braz, alcançando a incrível marca de 6,03 m. O segundo lugar foi do francês Renaud Lavillenie; já o terceiro lugar ficou com o americano Sam Kendricks. Para descobrir as alturas dos melhores saltos dos segundo e terceiro lugares, são dadas as seguintes dicas: DICA 1: a diferença entre as alturas dos saltos dos segundo e terceiro lugares foi de 130 milímetros. DICA 2: somando as alturas dos saltos realizados por Thiago Braz, por Renaud Lavillenie e por Sam Kendricks, obtemos um total de 1 786 centímetros. Assim, pode-se afirmar que os saltos que garantiram a medalha de prata (segundo lugar) para o francês e a de bronze (terceiro lugar) para o americano, respectivamente, foram de

                               Would it be wrong to eradicate mosquitoes?

      The mosquito is the most dangerous animal in the world, carrying diseases that kill one million people a year. Now the Zika virus, which is carried by mosquitoes, has been linked with thousands of babies born with brain defects in South America. There are 3,500 known species of mosquitoes, but only the females from just 6% of species draw blood from humans - to help them develop their eggs. Of these, just half carry parasites that cause human diseases.

      More than a million people, mostly from poorer nations, die each year from mosquito-borne diseases, including Malaria, Dengue Fever and Yellow Fever. Some mosquitoes also carry the Zika virus, which was first thought to cause only mild fever and rashes. However, scientists are now worried that it can damage babies in the womb. There’s a constant effort to educate people to use nets and other tactics to avoid being bitten. But would it just be simpler to make an entire species of disease-carrying mosquito extinct?

      In Britain, scientists at Oxford University and the biotech firm Oxitec have genetically modified (GM) the males of Aedes aegypti - a mosquito species that carries both the Zika and Dengue viruses. These GM males carry a gene that stops their offspring from developing properly. This second generation of mosquitoes then die before they can reproduce and become carriers of disease themselves.

      So are there any downsides to removing mosquitoes? Mosquitoes, which mostly feed on plant nectar, are important pollinators. They are also a food source for birds and bats while their young - as larvae - are consumed by fish and frogs. This could have an effect further ahead in the food chain. Mosquitoes also have limited the destructive impact of humanity on nature. Mosquitoes make tropical rainforests, for humans, virtually uninhabitable. Rainforests are home to a large share of our total plant and animal species, and nothing has done more to delay man-made destruction over the past 10,000 years than the mosquito.

            Operation Desert Storm Was Not Won By Smart Weaponry Alone

      Technology has long been a deciding factor on the battlefield, from powerful artillery to new weaponry to innovations in the seas and the skies. Twenty-five years ago, it was no different, as the United States and its allies proved overwhelmingly successful in the Persian Gulf War. A coalition of U.S. Army Apache attack helicopters, cruise missiles from naval vessels, and Lockheed F-117 Nighthawk “stealth fighters” soundly broke through Saddam Hussein’s army defenses in Kuwait during Operation Desert Storm, which became known as the “100-hour war”.

      But for all the possibilities that this “Computer War” offered, Operation Desert Storm was not won by smart weaponry, alone. Despite the “science fiction”-like technology deployed, 90 percent of the pieces of ammunition used in Desert Storm were actually “dumb weapons”. The bombs, which weren’t guided by lasers or satellites, were lucky to get within half a kilometer of their targets after they were dumped from planes. While dumb bombs might not have been exciting enough to make the headlines during the attack, they were cheaper to produce and could be counted on to work. But frequency of use doesn’t change why history will remember Desert Storm for its smart weapons, rather than its dumb ones.
