Apollo 13 was to be the third mission to land on the Moon. An explosion in one of the oxygen tanks crippled the spacecraft during flight and the crew were forced to orbit the Moon and return to the Earth without landing.
Summary of Events
The Apollo 13 mission was launched at 2:13 p.m. EST, April 11, 1970 from launch complex 39A at Kennedy Space Center. Apollo 13 Launch The space vehicle crew consisted of James A. Lovell, Jr. commander, John L. Swigert, Jr., command module pilot and Fred W. Haise, Jr. lunar module pilot.
The Apollo 13 Mission was planned as a lunar landing mission but was aborted en route to the moon after about 56 hours of flight due to loss of service module cryogenic oxygen and consequent loss of capability to generate electrical power, to provide oxygen and to produce water.
Spacecraft systems performance was nominal until the fans in cryogenic oxygen tank 2 were turned on at 55:53:18 ground elapsed time (GET). About 2 seconds after energizing the fan circuit, a short was indicated in the current from fuel cell 3, which was supplying power to cryogenic oxygen tank 2 fans. Within several additional seconds, two other shorted conditions occurred.
Electrical shorts in the fan circuit ignited the wire insulation, causing temperature and pressure to increase within cryogenic oxygen tank 2. When pressure reached the cryogenic oxygen tank 2 relief valve full-flow conditions of 1008 psi, the pressure began decreasing for about 9 seconds, at which time the relief valve probably reseated, causing the pressure to rise again momentarily. About a quarter of a second later, a vibration disturbance was noted on the command module accelerometers.
The next series of events occurred within a fraction of a second between the accelerometer disturbances and the data loss. A tank line burst, because of heat, in the vacuum jacket pressurizing the annulus and, in turn, causing the blow-out plug on the vacuum jacket to rupture. Some mechanism in bay 4 combined with the oxygen buildup in that bay to cause a rapid pressure rise which resulted in separation of the outer panel. The panel struck one of the dishes of the high-gain antenna. The panel separation shock closed the fuel cell 1 and 3 oxygen reactant shut-off valves and several propellant and helium isolation valves in the reaction control system. Data were lost for about 1.8 seconds as the high-gain antenna switched from narrow beam to wide beam, because of the antenna being hit and damaged.
As a result of these occurrences, the CM was powered down and the LM was configured to supply the necessary power and other consumables.
The CSM was powered down at approximately 58:40 GET. The surge tank and repressurization package were isolated with approximately 860 psi residual pressure (approx. 6.5 lbs of oxygen total). The primary water glycol system was left with radiators bypassed.
All LM systems performed satisfactorily in providing the necessary power and environmental control to the spacecraft. The requirement for lithium hydroxide to remove carbon dioxide from the spacecraft atmosphere was met by a combination of the CM and LM cartridges since the LM cartridges alone would not satisfy the total requirement. The crew, with direction from Mission Control, built an adapter for the CM cartridges to accept LM hoses.
The service module was jettisoned at approximately 138 hours GET, and the crew observed and photographed the bay-4 area where the cryogenic tank anomaly had occurred. At this time, the crew remarked that the outer skin covering for bay-4 had been severely damaged, with a large portion missing. The LM was jettisoned about 1 hour before entry, which was performed nominally using primary guidance and navigation system.

I need you to write about animal intelligence, but i only need an introduction and a body pharagraph.
Answer:
Introduction
There are a lot of different animals and what comes with different animals is different animal intelligence. Some animals need their intelligence to survive. Like chameleons for a instance their intelligence is to change color when predators are around. And to walk slowly and move with the leaves to confuse other animals.Its better for the animals to have their original intelligence.
Body
If for instance monkeys did not have their intelligence they would no be able to do anything. Monkeys as smart as toddlers: Scientists say apes can understand abstract properties. Monkeys are as smart as a three-year-old child when it comes to solving puzzles. Scientists said the findings showed they have the basic intelligence of a human tot as they can understand abstract properties. Without this they would be useless. There are even more amazing animal intelligences that you should learn about.

Dear Jackson,
Stop going to your school right now! It’s so dangerous, don’t you see? Your school at Norwood Códex Academy is filled with bullies, it’s not a safe environment to learn and progress. Your school also has a high rating for the most fights and drug abuse among students. Also, your school is known in the whole nation to be the worst school with the students having the worst grades, due to the fact that the teachers are not responsible with teaching their students properly. Their is no code of ethics in your school, no specific rules so students and teachers know what’s wrong or right. Please, move to my school. The rate of student fights is low, bullies are reprehended and there are cameras everywhere so there are no students using drugs. You will immediately progress intellectually, emotionally and physiologically. Here teachers are responsible for their teaching and they never slack off. Isn’t it great?
Sincerely, AD

When Martin Luther King Jr. was detained at the Birmingham Jail for the Birmingham struggle to remove segregation on April 16, 1963, he penned The Letter from Birmingham Jail.
What is the concept of the passage?King wrote a letter in which he discussed his nonviolence manifesto and his displeasure with white moderates who claimed to support the cause but frequently argued that the means used or the timing were inappropriate.
White moderates, according to him, were paternalistic and condescending. They believed that they should protect African Americans and that they deserved the same rights and freedoms, but they prevented them from enjoying those rights because they believed the time was not yet ripe.
Additionally, it was not practical for all of the white men in the community. King claimed that disagreement is less dangerous than a weak understanding because of this.
Thus, When Martin Luther King Jr. was detained at the Birmingham Jail.
