Read the following article and select the best answer. Article: William Herschel was born on November 15th, 1738 in Hanover in a family of musicians. In 1757,he fled to England and began earning a living as an organist and later composer and conductor. In 1772, he convinced his sister Caroline to join him as a singer. In their spare time the brother-sister team became occupied in astronomy. William died at his home in Slough, near Windsor on August 25th,1822,and Caroline on September 1st,1848. Herschel's first major discoveries were to show that Mars and Jupiter exhibit axial rotation . Herschel struck fame in 1781,when on March 13th he discovered the planet Uranus while engaged in work aimed at determining stellar parallax .This being the first new planet discovered since ancient times, Herschel, until then a mere amateur astronomer relatively unknown even in England, became world-famous. Adopting a historically proven strategy, Herschel named the new planet Georgium Sidum,in honor of the then ruling English king GeorgeIII. The trick worked once again, as King GeorgeIII gave William and Caroline the titles of"The King's Astronomer"and"Assistant to the King's Astronomer", an honor which came with a life's pension for both. In 1782 they moved to Bath, and shortly thereafter to Slough, and from this point on William and Caroline could devote themselves entirely to astronomy. The Herschels went on to discover two moons of Uranus in 1787. While Caroline became increasingly occupied with the search for comets at which she was quite successful, William became for a time interested in the Sun. Inspired by Wilson's 1774 work, he put forth the theory of sunspots ,an opinion that continued to exist well into the nineteenth century. In 1800,he became interested in the solar spectrum ,and uncovered the first evidence for solar energy output outside of the visible spectrum, in what is now known as the infrared .In 1801, he published two papers that effectively started the field of solar influences on Earth's weather. Question: What do we know about Caroline from the passage? - She was successful in music. - She was given the title of"The King's Astronomer". - She died later than her brother. - She published two papers.
**Answer**
She died later than her brother.

Read the following article and select the best answer. Article: A warm drink of milk before bed has long been the best choice for those wanting a good night's sleep. But now a study has found it really does help people nod off--if it is milked from a cow at night. Researchers have discovered that "night milk" contains more melatonin , which has been proven to help people feel sleepy and reduce anxiety. The study, by researchers from Seoul, South Korea, involved mice being fed with dried milk powder made from cows milked both during the day and at night. Those given night milk, which contained 10 times the amount of melatonin, were less active and less anxious than those fed with the milk collected during daytime, according to the study published in The Journal of Medicinal Food. Night milk quickened the start of sleep and caused the mice to sleep longer. While the effect of cows milk harvested at different time has not been tested on humans up to now, taking melatonin drugs has been suggested to those who are struggling to fall asleep at night. Previous studies have also indicated that milk can be excellent for helping sleep because of the calcium content, which helps people to relax. Milk is also sugar-free and additive-free with nutritionists recommending skimmed milk as the best choice before bed as it is the least fattening. The more fat you take in before bedtime, the greater burden you will put on your body at night. Question: Which of the following is true of melatonin according to the text? - It's been tested on mice for ten years - It can make people more energetic - It exists in milk in great amount - It's used in sleeping drugs
**Answer**
It's used in sleeping drugs

Read the following article and select the best answer. Article: Tens of thousands of smartphone applications are running ads from the overwhelming advertising networks that change smartphone settings and copy people's contact information without permission. Aggressive ad networks can disguise ads as text message notifications , and sometimes change browser settings and bookmarks. Often, the ads will upload your contacts list to the ad network's servers--- information that the ad network can then sell to marketers. Sounds scary? It's not a giant problem yet, but it's a growing one. As many as 5% of free mobile apps use an "aggressive" ad network to make money, according to Lookout, a San Francisco-based mobile security company. PhoneLiving was one of the most popular app developers to use these kinds of ad networks; their dozens of talking animal apps have been downloaded several million times. Later, PhoneLiving says it has mended its ways. The company admittedusing _ techniques to make money from its apps, but said it dropped those methods at the start of July because of bad reviews and declining downloads. The most popular type of apps that use aggressive ad networks are "Personalisation" apps, which include wallpapers. Comic and entertainment apps are also among the most likely to have rogue ad networks running behind the scenes. Like aggressive pop-ups on PCs, the bad software isn't easy to get rid of. Though the damage can typically be removed by deleting the app, it can be hard to tell which app is causing the problems. When developers create free mobile apps, they usually make money through ads displayed within the app. App makers don't usually tell people which ad network they are using, which makes it hard to avoid the known offenders. The best defense is to read reviews and avoid downloading apps that have attracted many complaints. Question: What is an example of bad behavior by the annoying mobile ads? - They change browser settings and bookmarks. - They change people's calendar settings. - They send scam text messages occasionally. - They download free versions of games.
**Answer**
They change browser settings and bookmarks.
