In this task, you're given an article, a question which often contains a blank, four options (associated with "A", "B", "C", "D") and the answer to that question. Your task is to classify whether the given answer is correct or not by providing "Yes" or "No", based on the article.

[EX Q]: Article: While every dog owner knows their dogs can read their moods perfectly, scientists have always been a piffle doubtful.Now thanks to some researchers at the University of Veterinary Medicine in Vienna, Austria; we finally have some convincing evidence. For their study, biologist Corson Miller and his team exposes eleven selected dogs to digital images of women that were either angry or happy.Half the dogs were rewired for touching the screen when shove a happy face, while the other half gilt their treat for selecting those that appeared angry. Interestingly, the dogs were not provided with the entire face.Some dogs were show Ti only upper halves while the others observed lower halves.That's because the scientists believe humans show their eruptions on their equities face. After some training ill.e how to recognize small differences like the wrinkles between the eyes or the changes in their shape that accompany the happy or angry expressions, the dogs were mostly able to identify the correct expression not only on a familiar face but on a strange face, the researchers concluded the dogs were smart-enough to read human emotions. They also found those being trained to read angry expressions took a longer time to learn.They guess it may be because dogs find angry faces disgusting, causing them to withdraw quickly.However, once the smart dogs realized they were getting rewired, the trepidation seem end to disappear.In fact, the dogs had such a good time playing the computer "game" That scientists had a hard time keeping them away from the touch screens after the study was completed. The researchers also noticed only dogs with a male owner had a harder time understanding the expressions correctly.Since the touches careen models were all females, this confirmed what has been observed in previous studies-dogs are more efficient at reading facial expressions of people that are the serene gender as their owner.
Question: How did the scientists conduct the experiment?
Options: (A) By leaving dogs to women who are either happy or angry. (B) By mixing the selected dogs together. (C) By rewarding only half of the dogs touching the screen. (D) By showing digital pictures of women's happy or angry faces.
Asnwer: B
[EX A]: No

[EX Q]: Article: Every spring Beijing is choked by huge sandstorms.The sky turns a strange and frightening yellow colour as clouds of sand sweep down from the deserts of Mongolia and north-western China.Strong winds blow up the dust and cover everything in sight--in 2006,a storm dumped 330,000 tonnes of dust on Beijing in one night. The number of sandstorms has grown alarmingly over the years as the deserts have expanded.This is partly man-made and partly because of climate .Many grasslands have been overgrazed by sheep and goats,or ploughed up,leaving the soil dangerously exposed.Too much water has been taken out of rivers,and the situation is made worse by increasingly long-lasting droughts that have affected the northern half of China as the climate grows warmer and drier.The result is probably the worst loss of rich land to deserts in the world and a dust bowl of extremely large proportions.The nearest sand dunes to Beijing are now only 70 km away and drifting closer each year.At this rate,the desert will reach the city by 2040,and Beijing could become the world's first modern city to disappear under sand.To hold back the deserts,a huge programme of forest planting called the Great Green Wall has been under way for over 30 years.The barrier is planned to be 4,500 km long when completed in several decades ,but the drought is having a very bad effect on the trees and the deserts carry on growing.
Question: All the following are the reasons for the expansion of the deserts EXCEPT _ .
Options: (A) the soil of the grasslands is exposed (B) too much water in rivers has been used (C) it doesn't rain for a long time (D) the climate in northern China is colder and drier
Asnwer: D
[EX A]: Yes

[EX Q]: Article: For thousands of years, mankind has produced plants and animals to create more desired and useful plants and animals. For example, modern com has been produced to such a large size that it is no longer able to reproduce without man's assistance. Modern dairy cows produce too much milk and if they are not often emptied of milk, they could leak, burst, become infected, and possibly die. Besides, most dogs raised by people can not survive in the wild even with special training. Since natural evolution is extremely slow and mankind's selective production programs only take a few generations to produce a completely new species, natural evolution has already _ mankind's production programs. In addition, mankind has successfully killed off several species all together. For example, there are no more European wolves in existence and mammoths probably died out because of mankind. Even certain diseases have been permanently got rid of from the planet, and dozens of other diseases will soon be too. Again, natural evolution did i>>t cause most of the destruction during man's rule of the world. Currently, scientists are creating new species with desired characteristics in the lab significantly faster than natural evolution creates new species. In a single generation, new species can be created and destroyed by mankind, while natural evolution could take thousands of years to do the same but only accidentally. Scientists are even able to replace defective or damaged genes with different genes to attempt to cure genetic defects. This is something that natural evolution could possibly never correct. Eventually scientists will even be able to improve the quality of people. For example, imagine not only correcting your eyesight with gene treatment, but also ensuring that all of your children do not receive your old genes of poor eyesight too. Scientists will one day be able to improve the memory and intelligence of your children, so that they will do better in school and achieve more in life. Doctors and scientists will be able to customize babies before they are born just like picking options at a car store.
Question: What can we infer from the passage?
Options: (A) Near-sighted parents will be able to produce babies with good eyesight in the future. (B) Doctors and scientists will be responsible for mass production of babies in the future. (C) It is natural evolution that is to blame for the destruction of European wolves and mammoths. (D) Children can now have their memory and intelligence improved with the help of gene treatment.
Asnwer: C
