Read the following article and select the best answer. Article: When I was learning calligraphy , my teacher told me a story. A calligrapher taught handwriting. One of his students who often practiced handwriting with old sheets of newspaper complained that he made very little progress though he had learned it with the calligrapher for a long time. His teacher said to him, "Try to use the best paper. Maybe you'll write better." The student did as he was told. It really worked. He made headway not long afterwards and felt curious. He asked his teacher about the reason. The calligrapher answered,"When you used old newspaper to practice handwriting, you would think you were writing a draft. It didn't matter if you wrote badly as old newspaper was plenty in supply. In that case you wouldn't pay much attention to it. Now you use the best paper and you'll treasure it. Each time you write you feel strongly about the rarity of chances and you'll devote to it with all your heart and soul; you'll do the handwriting much more attentively than practicing. Of course you've made rapid progress." Indeed, we spend our ordinary days just as they are worthless "old newspaper".We don't care if we scrawl and waste it, thinking that it will come endlessly--the "old newspaper" is inexhaustible. In such a mood we may each day pass by opportunities but fail to catch any of them. Life is not a military exercise but an actual war in which real weapons are used. In everyday life there's no chance for us to draft. That's because what we call "draft" actually is the answer sheet we write that cannot be changed. Every day of our life is something new. Let us take every day as a sheet of the best paper. Question: The calligrapher in the story told the student to write on the best paper because he thought _ . - the student would practice more carefully on the best paper - it was comfortable to write on the best paper - the student had enough money to buy the best paper - the student could write more on the best paper
(Answer)
the student would practice more carefully on the best paper

Ques: Read the following article and select the best answer. Article: Relation between the United States and Columbia suffered for many years because of an incident involving the Republic of Panama. By the end of the Spanish-American War in 1898, many Americans felt that an easier and faster way was needed to get ships from the Atlantic Ocean to the Pacific Ocean. Some people in the United States first believed that a canal across Nicaragua was the answer. However, President Theodore Roosevelt decided that a canal through Panama would be a better choice. In order to build the canal , the United States had to negotiate a treaty with Columbia , which at that time controlled Panama . Roosevelt offered Columbia $ 10 million plus $ 250,000 a year for 99 years for a six-mile-wide strip of land across Panama. Columbia rejected the United States' offer. This ranged President Roosevelt, and negotiations with Columbia ended. In 1903, a revolution broke out in Panama. The United States ships were sent by President Roosevelt to protect the Panamanian revolutionaries from Columbian forces. The revolution succeeded, and Panama declared its independence from Columbia. The United States then negotiated with the newly formed government. A treaty was signed, and the United States began building the canal. As a result of the incident, Columbia and the United States remained on bad terms for many years. Not until 1921, when the United States agreed to pay Columbia some compensation for its territory, did relations between the two countries improve. Question: It can be inferred from the passage that an important reason for the decision of the United States to build a canal was to _ . - develop trade relations with Europe - improve relations with South American countries - prevent European ships from reaching the Pacific Ocean - reduce travel time for its ships in case of war
Ans: reduce travel time for its ships in case of war
