The Bermuda Triangle has always been shrouded in mystery. The missing ships and planes have roused irrevocable inquisitiveness among people. Many theories pertaining to extraterrestrials, evil humans, anti gravity, magnetic field, oceanic flatulence and other technical sounding and weird hypothesis have been put forth. But a few investigators contrive ill luck, pirates, incompetence of navigators to be the cause of these missing ships and planes.A few diehard rationalists believe there is no mystery element that needs to be explained. No scientific derivations prove any aura of mystery enveloping Bermuda Triangle. The surprising subject rather is how Bermuda Triangle became so centralized a topic of mystery.Probably it began with the disappearance of five Navy planes in 1945. Logic states they vanished due to bad weather and failure of compass field. The trainee pilots lacked the expertise to face the sudden ordeal. The other declaration was that the planes collapsed due to fuel shortage. But in no way any mystery element coincides.This has been a revered subject for writers as a lot of written material can be found about it. It's perhaps surprising that no one took the investigation on the mystery. Rather they all cashed this mystery to write their best sellers. The mass media too played in phlegmatic attitude in solving this. They plundered the mystery element to spice up their news items. Soon the superstitious called it the 'Devil's Triangle'. All these exaggerations have helped to lend fear and fascination to the world's greatest mystery the Bermuda Triangle. .

Although the Earth is not perfectly spherical, the fact that it is spinning on its axis, coupled with the physical law that states that the outermost extension of an object has to be traveling much faster than its crux, ensures that satellites launched from points on or near the equator get an additional natural boost when compared to satellites launched from less centrally located points on the planet. In most cases, the satellites are designed to head East upon being launched. Since the Earth rotates to the East, this action gives the artificial satellites an additional boost upon launch. Today's satellites are extremely heavy, and any additional boost is not only welcome but also a contributing factor towards a successful launch. It is not only the geostationary satellites that get an additional kick from being launched close to the equator, but also the satellites being launched for other purposes. Today's satellites can be veritable behemoths with payloads that are calculated in tons, and even a small decrease in terms of the thrust from the boost generated by the rotation of the Earth means a heck of a lot more propellant requirements for the launch process. Considering how much an average satellite can weigh, the sheer acceleration they achieve is off the radar of most land-bound speed demons. Boosted by solid fuel propellants, the satellite would probably be doing close to a hundred miles an hour at launch, but just a minute later, it could be at up to ten times that speed, and the final speed could be anywhere up to eighteen times the launch speed.

Which of the following can most reasonably be inferred from the passage?

Since the Earth is not perfectly spherical, a satellite gets a significant natural boost at launch.

Satellites are increasingly being used for weather forecasting and military surveillance.

Only the geostationary satellites are able to gain adequate thrust from Earth's rotation.

Smaller and lighter satellites would not have so much need for Earth's rotational boost.

A satellite launch expects to extract the maximum possible advantage from natural and man-made resources.

have a path of revolution above or near the Earth's equator

The gravitational pull of the Earth

The centripetal force generated by Earth's rotation

The volume of the satellite

The geographical location of the launching point

The speed of rotation of the Earth

Uncertainty can be a source of terror and anguish. It keeps us up at night. But it is also an invitation for deeper exploration. It forces us to earn our certainties, rather than buy them cheaply and wholesale. Indeed, a dynamic, honest search for truth requires us to regard uncertainty as an enduring companion rather than an enemy to be fled or vanquished.
We can learn something about how to live with uncertainty from a field that few associate with it: mathematics. Mathematicians have been forced to struggle with uncertainty on many levels. This is true not just in probability and statistics—which address uncertainty quantitatively—but even in the bedrock of logic, arithmetic, and geometry, where most people expect rigid certainty to rule.
These struggles have given mathematicians a keen sense of the nature of truth: of when certainty can be achieved and when it is out of reach, as well as the boundless creativity we need to find it. There are lessons here for how all of us can pursue truth together, even in the face of the disagreements and uncertainties that surround us.

The author uses the example of mathematics in the passage most likely for which of the following reasons?

It focuses not only on subjects that deal with uncertainties but also on those where rules prevail.

The wide purview of the discipline affords mathematicians a varied exposure to uncertainties.

The study of mathematics enables one to discover the truth, even when it might seem unlikely.

More willpower and creativity are needed in mathematics to cross the barrier of uncertainties and land into certainty.

Uncertainties exist in mathematics despite its concrete rules, which are expected to produce definite results.
