Um grupo de amigos formado por três meninos - entre eles Caio e Beto - e seis meninas - entre elas Ana e Beatriz - , compram ingressos para nove lugares localizados lado a lado, em uma mesma fila no cinema. Ana e Beatriz precisam sentar-se juntas porque querem compartilhar do mesmo pacote de pipocas. Caio e Beto, por sua vez, precisam sentar-se juntos porque querem compartilhar do mesmo pacote de salgadinhos. Além disso, todas as meninas querem sentar-se juntas, e todos os meninos querem sentar-se juntos. Com essas informações, o número de diferentes maneiras que esses amigos podem sentar-se é igual a:

Em determinada universidade, foi realizado um estudo para avaliar o grau de satisfação de seus professores e alunos. O estudo mostrou que, naquela universidade, nenhum aluno é completamente feliz e alguns professores são completamente felizes. Uma conclusão logicamente necessária destas informações é que, naquela universidade, objeto da pesquisa,

Todo amigo de Luiza é filho de Marcos. Todo primo de Carlos, se não for irmão de Ernesto, ou é amigo de Luiza ou é neto de Tânia. Ora, não há irmão de Ernesto ou neto de Tânia que não seja filho de Marcos. Portanto, tem-se, necessariamente, que:

Em termos conceituais, o orçamento público pode ser entendido como o instrumento de que dispõe o Poder Público para expressar, em determinado período de tempo,

The Knowledge Race

Dec 2006 – Feb 2006 (Adapted)

There are losers in every race, but let not the worries over who is winning and losing the knowledge race obscure the more powerful underlying dynamic: knowledge is liberating. It creates the possibility for change and improvement everywhere. It can create amazing devices and techniques, save lives, improve living standards and spread information. Some will do well on one measure, others on another. But on the whole, a knowledge-based world will be a healthier and richer world.

The caveat I would make is not about one or another country’s paucity of engineers or computers. These problems can be solved. But knowledge is not the same thing as wisdom. Knowledge can produce equally powerful ways to destroy life, intentionally and unintentionally. It can produce hate and seek destruction. Knowledge does not by itself produce good sense, courage, generosity and tolerance. And most crucially, it does not produce the farsightedness that will allow us all to live together – and grow together –on this world without causing war, chaos and catastrophe. For that we need wisdom.

The author intends to make a caveat in relation to the distinction between knowledge and wisdom. Thus, he is posing

There is an intense debate over the future of energy and its impact on Europe’s economy. On the one hand is a longstanding project for lower prices led by the European Commission designed to liberalize the market and enable producers and distributors to compete freely within and across national borders. On the other is a camp that argues with growing confidence against further freeing the market. In its view, long-term security and stable prices can best be preserved in managed national markets that are dominated by strong quasi-monopolistic companies which can withstand bullying producers and sudden shifts in demand and supply.

This tension has implications for businesses across Europe. Today business customers in different countries pay prices that vary as much as 100% across what is supposed to be a single European market. A freer market in energy promises to reduce prices back to something like a Europe-wide clearing level. Energy is a critical input to businesses, especially manufacturing, and rising prices are putting unwelcome pressure on already tight margins, as companies try to compete with emerging low-wage economies in Asia.
