Problem: ISIS, as the Islamic State jihadists in Iraq and Syria are known, has become the new face of international terrorism in the eyes of the United States and its Western allies.

Now the focus in America and abroad has become what will President Barack Obama and other leaders do about it?

Here are key questions on the matter:

1) Who killed James Foley?

Britain's ambassador to the United States, Peter Westmacott, told CNN on Sunday that British officials were close to identifying the ISIS militant who beheaded Foley, an American journalist captured in Syria in 2012.

He couldn't elaborate on the identity of the killer, who is seen decapitating Foley in a video posted last week on YouTube.

"We're putting a great deal into the search," he said, referring to the use of sophisticated technology to analyze the man's voice.

In the video, Foley, 40, is seen kneeling next to a man dressed in black, who speaks with what experts say is a distinctly English accent.

Linguists said that based on his voice, the man sounds to be younger than 30. He also appears to have been educated in England from a young age and to be from southern England or London.

Britain close to identifying James Foley's killer, ambassador says

2) Will the United States expand air strikes to ISIS targets in Syria?

Pressure is increasing on Obama to go after ISIS in both Iraq and Syria, ignoring an essentially non-existent border between them.

Last week, Defense Secretary Chuck Hagel and Joint Chiefs Chairman Gen. Martin Dempsey said that taking on ISIS in Syria was the only way to defeat the Sunni jihadists.

Problem: A degree (in full, a degree of arc, arc degree, or arcdegree), usually denoted by (the degree symbol), is a measurement of a plane angle, defined so that a full rotation is 360 degrees.

It is not an SI unit, as the SI unit of angular measure is the radian, but it is mentioned in the SI brochure as an accepted unit. Because a full rotation equals 2 radians, one degree is equivalent to radians.

The original motivation for choosing the degree as a unit of rotations and angles is unknown. One theory states that it is related to the fact that 360 is approximately the number of days in a year. Ancient astronomers noticed that the sun, which follows through the ecliptic path over the course of the year, seems to advance in its path by approximately one degree each day. Some ancient calendars, such as the Persian calendar, used 360 days for a year. The use of a calendar with 360 days may be related to the use of sexagesimal numbers.

Another theory is that the Babylonians subdivided the circle using the angle of an equilateral triangle as the basic unit and further subdivided the latter into 60 parts following their sexagesimal numeric system. The earliest trigonometry, used by the Babylonian astronomers and their Greek successors, was based on chords of a circle. A chord of length equal to the radius made a natural base quantity. One sixtieth of this, using their standard sexagesimal divisions, was a degree.
1. How many degrees are in a full circle?

Answer: 1. 360 degrees
2. no

Problem: A comic strip is a sequence of drawings arranged in interrelated panels to display brief humor or form a narrative, often serialized, with text in balloons and captions. Traditionally, throughout the 20th century and into the 21st, these have been published in newspapers and magazines, with horizontal strips printed in black-and-white in daily newspapers, while Sunday newspapers offered longer sequences in special color comics sections. With the development of the internet, they began to appear online as webcomics. There were more than 200 different comic strips and daily cartoon panels in American newspapers alone each day for most of the 20th century, for a total of at least 7,300,000 episodes.

Strips are written and drawn by a comics artist or cartoonist. As the name implies, comic strips can be humorous (for example, "gag-a-day" strips such as "Blondie", "Bringing Up Father", "Marmaduke", and "Pearls Before Swine").

Starting in the late 1920s, comic strips expanded from their mirthful origins to feature adventure stories, as seen in "Popeye", "Captain Easy", "Buck Rogers", "Tarzan", and "The Adventures of Tintin". Soap-opera continuity strips such as "Judge Parker" and "Mary Worth" gained popularity in the 1940s. All are called, generically, comic strips, though cartoonist Will Eisner has suggested that "sequential art" would be a better genre-neutral name.
