Read the passage, and choose the correct answer A, B, C or D for each question. Wi-Fi is a method for devices such as smartphones to connect wirelessly to the Internet using radio waves. Connecting to the Internet using Wi-Fi requires a hotspot, but it is always faster than the 3G cellular networks which smartphones can also use to connect, and occasionally faster than 4G. Using Wi-Fi when it is available can also prove to be cheaper and make your phone run more efficiently in the long run than relying on cellular networks. When you use a Wi-Fi network to access the Internet from your phone, the data usage does not count against your bundled data. Mobile providers often allocate a certain amount of data for free each month and charge you a fee for any data usage beyond this. By connecting via Wi-Fi wherever it is available, you can save your bundled data for situations when you might not be close to any Wi-Fi hotspots. In many situations, your speed using a strong, dedicated Wi-Fi connection is faster than that of using your mobile network. It is very noticeable when transferring larger files. If you need to download large files or stream media to your smartphone in a hurry, it is much better to do so via Wi-Fi. Battery life is extremely important for smartphones because you will not be able to connect to the Internet or use certain functions such as the camera flash if your battery is too low. Using Wi-Fi to connect to the Internet drains less battery life than using a mobile network, especially in situations where the cellular coverage fluctuates. Since Wi-Fi is generally faster than using mobile networks, you will also not spend as much time transferring the data, which further decreases battery usage. The following are the advantages of using Wi-Fi on your smartphone EXCEPT that _____.

Read the following passage and mark the letter A, B, C, or D to indicate thecorrect word or phrase that best fits each of the numbered blanks. Humanitarian Dorothea Dix was born in Hampden, Maine, in 1802. At the age of 19, she established a school for girls, the Dix Mansion School, in Boston, but had to close it in 1835 due to her poor health. She wrote and published the first of many books for children in 1824. In 1841, Dix accepted an invitation to teach classes at a prison in East Cambridge, Massachusetts. She was deeply disturbed by the sight of mentally-ill persons thrown in the jail and treated like criminals. For the next eighteen months, she toured Massachusetts institutions where other mental patients were confined and reported the shocking conditions she found to the state legislature. When improvements followed in Massachusetts, she turned her attention to the neighbouring states and then to the West and South. Dix's work was interrupted by the Civil War; she served as superintendent of women hospital nurses for the federal government. Dix saw special hospitals for the mentally-ill built in some fifteen states. Although her plan to obtain public land for her cause failed, she aroused concern for the problem of mental illnesses all over the United States as well as in Canada and Europe. Dix's success was due to her independent and thorough research, her gentle but persistent manner, and her ability to secure the help of powerful and wealthy supporters. In what year was the Dix Mansion School closed?
