QUES: Pesticides are often referred to according to the type of pest they control. Pesticides can also be considered as either biodegradable pesticides, which will be broken down by microbes and other living beings into harmless compounds, or persistent pesticides, which may take months or years before they are broken down: it was the persistence of DDT, for example, which led to its accumulation in the food chain and its killing of birds of prey at the top of the food chain. Another way to think about pesticides is to consider those that are chemical pesticides or are derived from a common source or production method.

QUES: The Palácio do Planalto is the official workplace of the President of Brazil. It is located at the Praça dos Três Poderes in Brasília. As the seat of government, the term "Planalto" is often used as a metonym for the executive branch of government. The main working office of the President of the Republic is in the Palácio do Planalto. The President and his or her family do not live in it, rather in the official residence, the Palácio da Alvorada. Besides the President, senior advisors also have offices in the "Planalto," including the Vice-President of Brazil and the Chief of Staff. The other Ministries are along the Esplanada dos Ministérios. The architect of the Palácio do Planalto was Oscar Niemeyer, creator of most of the important buildings in Brasília. The idea was to project an image of simplicity and modernity using fine lines and waves to compose the columns and exterior structures. The Palace is four stories high, and has an area of 36,000 m2. Four other adjacent buildings are also part of the complex.
