In 1984, Ampleforth and Parsons are arrested. What is suggested about personal security by this?

Throughout the novel, Winston has been looking forward to "the place where there is no darkness" as a refuge from the distortion, hatred and suspicion under which everyone lives in Oceania.

It is revealed when they are all arrested and taken to a brightly lit antiseptic looking metal room--cold, uncomfy, and never dark. Certainly not a refuge.

Ampleforth is arrested for his inability to remove the word "God" from a line of poetry. Parsons is arrested for thoughtcrime and had been turned in by his own daughter.

These two men are arrested for seemingly innocent things. Ampleforth was simply trying to keep the rhyme scheme in Kipling's poem true, and Parsons claims to be proud of the daughter who accused him of thoughtcrime--something he says must have come upon him without his knowledge whatsoever.

No one is safe...there is no security in Oceania within the Party.

What is the conflict of the story "The Lady with a Dog" by Anton Chekhov?

The central conflict is the pull between loyalty and infatuation, security and the unknown, and the failure to truly know if the latter is something real or illusory.   Both the man and woman are trapped in shallow lives, both seek a more satisfying relationship, a spark that makes life worth living.  For example, when the pair are at dinner,

"Then both continued eating in silence, like strangers, but after dinner they walked side by side; and there sprang up between them the light jesting conversation of people who are free and satisfied, to whom it does not matter where they go or what they talk about."

However, despite these positive indications of a chance for more "alive" living, neither one is ready to give up what they know or feel comfortable with in their lives.  The story concludes with a sour grapes sort of line:  ""There's something pathetic about her, anyway," he thought, and fell asleep." 

Is the reason when demand rises and causes price to rise because there will temporarily be a shortage and that will result in a higher price?is...

That is basically correct.  Economic theory says that
increased demand will lead to a shortage and that firms will react by raising their
prices.

The way that this is likely to work in real life,
though, is that the owners of stores will look and see that this particular product is
flying off their shelves faster than they would have expected.  When this happens, they
will think that they might well be able to sell just as many at a higher
price.

But economically speaking, that is exactly what
happens -- there is a temporary shortage resulting in a higher
price.

Compare the elements of Gothic Literature in both "Ligeia" and "The Raven" by Poe?Gothic is focusing on dark, mysterious, terrifying events. The...

"The Raven" is set in a darkly-lit house, on the edge of the ocean, during a windy night.  One character is a speaking raven, who has appeared out of nowhere and seems to be answering the narrator's questions with an applicable "Nevermore".  The raven rests quietly and refuses to leave.  The narrator interprets it as a sign of his grief, and he is left feeling despondent.

In "Ligeia", the narrator is obsessed with death.  In the story, the wife supernaturally rises from the dead.  The setting ends up in a lonely and abandoned abbey in England where light is obstructed because of the lead in the windows.  Furniture that appears to change shape, and the narrator's feeling that a shadow is following his wife about also enhance the gothic nature of this story.

Develop your main idea with supporting details (proof,facts,examples,etc.). Topic: Is it important for us to take care of our water systems?Science

One idea that you can easily develop is that water is
life.  For, nothing that lives can survive without water.  Thus, it is our most precious
commodity.

Surely, there is much support that you can
locate.  For instance, some years ago, it appeared that Lake Erie had so much pollution
that reversing the situation seemed impossible.  However, scientists were able to
restore the lake, restock it with fish, and make it possible for people to drink its
water.

For assistance with writing see the how-to topics. 
A couple of sites are listed below:

In another instance of
not understanding our precious water is Atlanta, Georgia's city leaders did not plan
well enough to have sufficient water for its growing population, and after two years of
drought, Atlanta began a "water war" with its neighboring state of Alabama in order to
obtain water rights.  Now, after two years of fighting, Atlanta has yet to build any
reservoirs to hold all the rain that has fallen in these past two years of very wet
weather.

What will happen to the convict if he is found in London?

The basic answer to this is that he will be sentenced to
death if he is found and identified in London or anywhere else in
Britain.

The reason for this is found in his original
sentence.  He was sentenced to be "transported."  This meant that he was sent to
Australia instead of being executed or imprisoned in Britain.  But the other side of
that deal is that he was never allowed to return to
Britain.

Now that he has returned, he is risking death. 
You will find out later in the book whether he will get caught and face death or
not.

What's the importance of Bataan Death March in terms of WWII?

This incident did not really have much of an impact, if
any, on the actual outcome of World War II.  And it did not have much of an impact on
how the war was fought.  The only real importance of this is in how it affects the way
we remember the war (and of course it affected the people involved, like one of my
great-uncles who died in it).

The Bataan Death March
happened after the US and Filipino troops surrendered their last position on Luzon in
the Philippines.  This was the island fortress of Corregidor.  After the surrender, the
troops were marched 60 miles or so off to a railhead that would bring them to a prison
camp.  Along the way, many of the prisoners died because of the brutal way they were
treated.

This became important as a symbol of Japanese
brutality during WWII.
