Answer:
1. Focus
2. Aphelion
3. Ellipse
4. Semimajor axis
5. Perihelion
6. Eccentricity
Explanation:
In Kepler's first law of planetary motion, he says that planets orbit around the sun, not in perfect circles, but in ellipses (3.) the Earth also orbits the sun in this shape. The shape of the ellipse is determined by two focii. The closer these two points are to each other, the more the ellipse will resemble a circle.
The moon for example, orbits around the Earth. The moon is not always at the same distance from the Earth in all points of the orbit. So the shape is an ellipse, which is made with Earth as one of its focus(1.).
Eccentricity(6.) describes the flatness the orbit is, or how elliptical the orbit is. Remember Kepler's first law, he says that planets move in elliptical orbits and not perfect circles. So it is simply how different from a perfect circle an orbit is. Pluto is known to have a large eccentricity.
Because of the shape of an ellipse, there are going to be points where a planet is closest to the sun and where a planet is farthest from the sun. This is where Kepler's 2nd law of planetary motion comes in. When the planet is closest to the sun, this is called the perihelion (5.) where a planet would be traveling the fastest at this point of the orbit. When the planet is at its farthest point from the sun, this is called the aphelion (2.) where a planet would be traveling the slowest.
The third law of Kepler describes the relationship between the period and the average distance of the sun. The semimajor axis(4.) is the average distance of the planet object from the sun and is measured in Astonomical units (AU). The period is measured in years.
For the given situation above, I think there is a lack of information regarding the one you posted. Here is what I got about the Cordillera Region.
The word Cordillera is actually a Spanish word that means mountain ranges. The climate is warm and temperate in Cordillera. Cordillera has a significant amount of rainfall during the year. This is true even for the driest month. The average annual temperature in Cordillera is 21.2 °C. The average annual rainfall is 1431 mm.

The correct answer is - C. Colombia.
Colombia has a long tradition in coca production and than illegal trade with cocaine and unfortunately this is what is the country's trademark. Unlike some of the South American countries where it is noticed a drop in coca production, Colombia is actually having an increase in production, and a very significant one, every year in the past 6 years there's more and more plantations with coca and there is more and more cocaine production that ends up illegally all over the world. This process is mainly sponsored and under the wings of the Colombian cartels.
