Read the following passage:

"Yawning is both one of our most familiar and mysterious behaviors. All humans and most vertebrates yawn, yet we don’t know whether this everyday activity has a physical or a social purpose.

"One possibility is that yawning is strictly a physical trigger and response. Some studies show that the frequency of yawning depends on oxygen and carbon dioxide levels and temperature. Yawning might cool the brain by pulling blood towards the mouth and neck where it is cooled by indrawn breath. It could trigger a release of hormones that elevate mood and appetite. Or the stretching that accompanies a yawn could help maintain muscle readiness to respond to danger.

"On the other hand, it’s also been suggested that yawning is primarily a way of communicating. Yawning is contagious. Research shows that seeing, hearing, and simply reading about a yawn causes observers to yawn themselves. Yawns are most catching in social creatures like humans, chimps, dogs, and parrots. They’re somewhat less catching among children with autism and adults with psychopathic tendencies, and they don’t occur at all in solitary species like tortoises. Yawning may be a way of forming bonds within a group by synching up sleep and wake cycles and other behaviors. It might also serve as a way of establishing dominance by showing off the size of teeth and jaws or signaling boredom.

"While scientists debate the purpose of yawning, one thing is almost certain. You probably yawned more than once reading about it."

Which option below is a major supporting detail in the reading?


Yawning might help cool the brain.


Yawning may be a method of communication.


Yawning is common in the animal kingdom.


Turtles don’t catch yawns.


Answers

Answer 1

The correct option is B.The major supporting detail in the reading is “Yawning may be a method of communication”.

This option states that yawning might be a way of communicating. Research shows that yawns are contagious; observing, hearing, and even reading about a yawn makes observers yawn themselves.

This behavior is most prevalent in social creatures, including humans, chimps, dogs, and parrots.

Yawns are also slightly less contagious in children with autism and adults with psychopathic tendencies, and they don’t occur at all in solitary species like tortoises.

Yawning can be a way of forming bonds within a group by synching up sleep and wake cycles and other behaviors.

It might also serve as a way of establishing dominance by showing off the size of teeth and jaws or signaling boredom.

Hence, the option that states that "Yawning may be a method of communication" is the correct answer.

Quotes for chapter 7 I am mala

Answers

Chapter 7: The Mufti Who Tried to Close Our School

Malala tells of the struggle between a local conservative mufti, or Islamic scholar, and her father, Ziauddin. The mufti accuses Ziauddin of committing blasphemy by allowing girls to go to school instead being in purdah, or seclusion. Malala says that she does not like the interpretation of Islam that emphasizes jihad and restricts women’s freedom by requiring that they stay home and wear burqas.

When men from the community confront Ziauddin about his school, he defends his position by referencing the Quran. He then offers to have his female students enter school through a different entrance. Malala then relates the bloody division of India that created Muslim Pakistan and resulted in the death of millions of Hindus and Muslims. She explains the disagreement between Sunnis and Shias over who is the rightful heir to the Prophet Mohammad. She highlights the subdivisions within the Sunnis in Pakistan. While General Musharraf relaxes constraints on women in Pakistan, Malala’s more conservative Pashtun area elects a mullah government (MMA) that gains support because of America’s invasion of Afghanistan and its fight against the Taliban. Violence breaks out when General Musharraf sends the army to the ungoverned FATA lands and the United States attacks Pakistan. Ziauddin worries about the growing militancy that is coming to Swat

Explain two ways in which belief in the afterlife influences Christians today

Answers

Answer:

Explanation:

This is  actually a very difficult question. Influences doesn't mean action although you mean it so. I just means guidance. Much has changed since the time of Christ. There is a great deal of interpretation that has been introduced into Christian thought; indeed, wars have been fought in terms of ritual since about the 3rd or 4th century.

Whole new religions have been created in the middle ages and beyond. So belief in after life depends on who you ask. If you ask a Jehovah's Witness for example, they would say that only 144000 are entitled to heaven the way most other Christians believe the afterlife will be like. The rest will live on an earthly paradise to be ruled by Jesus and the 144000.

If you ask a Catholic, their afterlife is divided into three. Where you go depends on what you have done. The most virtuous wind up in paradise. The worst of sinners wind up in Hell.

I'm not entirely sure how Protestants view the afterlife. There are so many denominations, that it is difficult to generalize.

Modern man tends to believe whole heartedly or not at all. Modern man tends to be guided by what the Old and New Testaments say, or not at all.

Sonnet XII

by William Shakespeare

When I do count the clock that tells the time,
And see the brave day sunk in hideous night;
When I behold the violet past prime,
And sable curls all silvered o'er with white;
When lofty trees I see barren of leaves
Which erst from heat did canopy the herd,
And summer's green all girded up in sheaves
Borne on the bier with white and bristly beard,
Then of thy beauty do I question make,
That thou among the wastes of time must go,
Since sweets and beauties do themselves forsake
And die as fast as they see others grow;
And nothing 'gainst Time's scythe can make defence
Save breed, to brave him when he takes thee hence.

What is an Exam?

A test is an exam. A lot of college and high school courses contain both a midterm and a final test. The term exam, a student slang term from the 19th century, is short for examination. An exam typically occurs in a classroom and comprises of problems that test a learners' understanding.

Examinations are a crucial component of education. Evaluation assessments are given at the conclusion of all programmes, including summer schools and faculty development initiatives, to determine what the students have learned. Exams therefore serve to promote proper learning rather than inhibit it.

Exams are formal tests that students take to demonstrate their understanding of a particular subject, and they are frequently given in written or spoken form.
