QUES: Scholars disagree over the effects of social status on racial classifications in Brazil. It is generally believed that achieving upward mobility and education results in individuals being classified as a category of lighter skin. The popular claim is that in Brazil, poor whites are considered black and wealthy blacks are considered white. Some scholars disagree, arguing that "whitening" of one's social status may be open to people of mixed race, a large part of the population known as pardo, but a person perceived as preto (black) will continue to be classified as black regardless of wealth or social status.
What type of skin color has a better chance of a good life in Brazil?

ANS: lighter skin

QUES: Instead, he formulated the spearhead model of evolution, a version of genetic pluralism. According to this model, living organisms themselves have goals, and act according to these goals, each guided by a central control. In its most sophisticated form, this is the brain of humans, but controls also exist in much less sophisticated ways for species of lower complexity, such as the amoeba. This control organ plays a special role in evolutionit is the "spearhead of evolution". The goals bring the purpose into the world. Mutations in the genes that determine the structure of the control may then cause drastic changes in behaviour, preferences and goals, without having an impact on the organism's phenotype. Popper postulates that such purely behavioural changes are less likely to be lethal for the organism compared to drastic changes of the phenotype.
What are mutations in the genes not able to change?

ANS: unanswerable

QUES: The law of criminal procedure in the United States consists of a massive overlay of federal constitutional case law interwoven with the federal and state statutes that actually provide the foundation for the creation and operation of law enforcement agencies and prison systems as well as the proceedings in criminal trials. Due to the perennial inability of legislatures in the U.S. to enact statutes that would actually force law enforcement officers to respect the constitutional rights of criminal suspects and convicts, the federal judiciary gradually developed the exclusionary rule as a method to enforce such rights. In turn, the exclusionary rule spawned a family of judge-made remedies for the abuse of law enforcement powers, of which the most famous is the Miranda warning. The writ of habeas corpus is often used by suspects and convicts to challenge their detention, while the Civil Rights Act of 1871 and Bivens actions are used by suspects to recover tort damages for police brutality.
When was the Miranda warning penned?

ANS: unanswerable

QUES: Antimatter is not found naturally on Earth, except very briefly and in vanishingly small quantities (as the result of radioactive decay, lightning or cosmic rays). This is because antimatter that came to exist on Earth outside the confines of a suitable physics laboratory would almost instantly meet the ordinary matter that Earth is made of, and be annihilated. Antiparticles and some stable antimatter (such as antihydrogen) can be made in tiny amounts, but not in enough quantity to do more than test a few of its theoretical properties.
Where is ordinary matter created?
