Example Input: Article: There was great excitement on the planet of Venus this week. For the first time Venusian scientists managed to land a satellite on the planet Earth, and it has been sending back signals as well as photographs ever since. The satellite was directed into an area known as Manhattan (named after the great Venusian astronomer Prof. Manhattan, who first discovered it with his telescope 20 000 light years ago).Because of excellent weather conditions and extremely strong signals, Venusian scientists were able to get valuable information as to feasibility of a manned flying saucer landing on Earth.A press conference was held at the Venus Institute of Technology. "We have come to the conclusion,based on last week's satellite landing," Pro. Zog said,"that there is no life on the Earth." "How do you know this?" the science reporter of the Venus Evening Star asked. "For one thing, Earth's surface in the area of Manhattan is composed of solid concrete and nothing can grow there. For another, the atmosphere is filled with carbon monoxide and other deadly gases and nobody could possibly breathe this air and survive." "What does this mean as far as our flying saucer program is concerned?" "We shall have to take our own oxygen with us, which means a much heavier flying saucer than we originally planned. " "Are there any other hazards that you discovered in your studies?" "Take a look at this photo. You see this dark cloud floating over the surface of Earth? We call this the Consolidated Edison Belt. We don't know what it is made of, but it could give us a lot of trouble and we shall have to make further tests before we send a Venus Being there." "If what you say is true, won't this set back the flying saucer program several years?" "Yes, but we shall proceed as soon as the Grubstart gives us the added funds." "Prof. Zog, why are we spending billions and billions of zilches to land a flying saucer on Earth when there is no life there?" "Because if we Venusians can learn to breathe in an Earth atmosphere, then we can live anywhere."
Question: During the week of great excitement the Venusian scientists succeeded in getting important information on whether they can _ .
Options: (A) land a satellite with Venus astronauts on Earth (B) make a firstrate flying saucer (C) get a Earth Being to Venus (D) direct a flying saucer into Manhattan
Example Output: A

Example Input: Article: In England, we look forward to our birthdays for 364 days a year! We invite special people to celebrate it with us. The Presents Presents are opened as soon as the children are awake. They can't wait for the birthday cake later in the day! The Cards Friends and family send birthday cards.

Visitors to the party bring presents for the birthday child. The children play games such as musical chairs and pass the parcel . The Cake The birthday cake is decorated on a theme . A candle for each year is lit and placed on top and the child blows out the candles making a wish. We don't put objects inside the cake as stated on many websites. The Bumps It used to be traditional for the birthday child to have the bumps. Friends would hold the child by the legs and under the arms and lift the child up and down bumping them gently on the ground. The number of bumps given is the age of the child plus one for extra good luck. As this can be dangerous, clapping is often done instead. The Sweets Some children do take sweets to school to share with their classmates on their birthdays.

Example Input: Article: Car Pollution Some cars do not run the way they should. Bad smoke from a car can get into the air. This bad smoke is called pollution. Pollution turns the air a gray color1. It is very dirty. It is not good for people to breathe this dirty air. To keep pollution down, the states tests cars every two years. This test checks to make sure the cars do not pollute the air. If a car does not pass the test, the owner cannot drive it the next year. Some car owners drive their cars even though they cannot pass the test. It is also very bad for the air. People want to find a way to get these cars off the road. So a state program was started that now seems to be helping. In this program the States buys cars that cannot pass the test or will help pay for repairs. This program has been helping people buy better cars or fix their old ones. It has also been helping to cut down on pollution. To meet the needs for the program, a car must be drivable and the owner must meet certain income restrictions . In order to get help from the program, a motorist must have a family income of no more than 185% of the national poverty guidelines . For a family of four, that would be no more than $32,653 each year. The state program that takes polluting cars off the road has just finished its first year, and people say it has been successful. For the past year, the state program has been buying cars that can't pass the test. Some car owners get as much as $1,000 for their old ones, while others receive as much as $500 for repairs. The cars bought by the States through the program are put out of use and sent to dismantlers .
Question: Cars get tested every two years to make sure _ .
Options: (A) the owners can get some money (B) they can get repaired on time (C) they don't pollute the air (D) the government can decide to buy them or not
Example Output:
C
