Marbury v Madison<br> Background info:<br> Decision: <br> Why it matters: <br> Plz help :p
lora16 [44]

Answer and Explanation:

Background info: When John Adams was defeated by Thomas Jeffersoon in the presidential election, he appointed some allies to senior government posts, such as federal judges. He believed that this way it would be better to maintain some political control in the country. However, after his departure, a law was passed that would allow the number of judges to be reduced. In this scenario, Thomas Jefferson can name new judges and prevent the ones chosen by Adams from being kept. This sparked a discussion about the validity of the law, creating the Marbury v Madison case.

Decision: Foi decidido que os Juízes nomeados por Jefferson deveriam receber seus diplomas e continuar no cargo, sendo que qualquer lei que impedisse isso seria uma lei inconstitucional e portanto, nula.

Why it matters: This case is extremely important for the establishment of the policy we know today. This is because it was through him that the constitutional control exercised by the Judiciary Power was created.

What are 3 reasons why the U.S becomes involved in international conflicts
Strike441 [17]

Answer:

Ukraine. Gaza. Syria. Yemen. Pakistan. If it feels like the United States is always at war somewhere, that's because it is. Not just Iraq and Afghanistan - the two wars we all know about. And, granted, we're not only talking boots on the ground. It's our money, our weapons and - more often in recent weeks - our Secretary of State, engaged in high-stakes diplomacy to uneven results. At his last count, investigative journalist Kevin Gosztola put the U.S. war count at 74. These are mostly unannounced and undeclared wars against enemies that have different aspirations, strategies and ideologies.

Why? The official line varies. Some conflict engagement is, we're told, about nation-building (Iraq and Afghanistan.) Other operations are to remove a despotic ruler (Syria, Libya.) Some engagement is designed to pick off a terror group/groups (Oman, Pakistan, Yemen) and/or to spread "true" democracy (Iraq and Afghanistan, again.) There are wars we engage in to free people from a cycle of fear (Central African Republic) to stem the flow of hundreds-year-old bloodletting (Israel/Palestine) and to keep old foes in check (Ukraine/Russia).

slava [35]

Answer:

The answer is a sense of inferiority.

Explanation:

According to Erikson's structure of psychosocial development, Daryl is probably at stage four, called Industry vs. Inferiority. During this stage, which appears around age five, children will have the chance to prove their competencies: learning to write, do basic math and develop artistic talent.

When the children's effort is encouraged, they will probably achieve a sense of industry (competency). Failure to do this might result in a sense of inferiority.
