Article: Alice Wilder, a 17-year-old student at Northwest School of the Arts in North Carolina, considers herself a feminist . She is one of 26 bloggers for SPARK, an international group founded in 2010. The group fights the use of the female body as a marketing tool in the media. Alice found out about SPARK when the organization launched a campaign demanding Seventeen Magazine feature a more diverse group of models. She applied to be a blogger for the group in May and won one of the positions. Each month, Alice pitches (...) her girl -and women - centric blog post ideas via online chat to an editor at SPARK. So far, she has written about topics such as female actresses, choosing what to wear, and dealing with anger. Alice said she hopes large companies and media stop editing images of women. Increases in bust size, decreases in waist size, smoothing and whitewashing skin are what Alice notes. "We want them to know that these images are bad for our development," Alice said. "Three out of four teen girls feel bad about themselves after reading a fashion magazine for three minutes," she said, according to SPARK's research. Alice first felt it necessary to advocate for women in the fifth grade, after seeing a girl's T-shirt with writing on the front that read: "Who needs brains when you have these?" "I was raised with this idea that if you don't like something, you can change it," Alice said. So Alice started following feminist bloggers. Alice juggles class work with blogging and creating videos and serves as editor-in-chief of her school's newspaper. It is amazing that she can handle everything well at the same time. She's also focused on creating projects that aim to inspire girls - like designing a "girl power bathroom" at her school. The newly designed third-floor restroom is completed with pastel paint color1s and inspirational quotes from women around the world. "Sisterhood is powerful," Alice said. "It can make you feel less alone."
Question: This article is mainly about _ .
Options: (A) what being a feminist means in today's American society (B) Alice Wilder's participation in feminist activities (C) how girls and women fight for their rights in the US (D) the ways that the US media misleads girls
answer:
B

Article: Many people cannot start their day without first having a cup of coffee or tea.These drinks help them think clearly and feel more awake.This is because of caffeine,which helps to give a jump start to the nervous system.Now,a report says it may also boost long-term memory. Mike Yassa is a neurobiology professor.He and other researchers wanted to know if caffeine could improve a person's memory.He explains,"After you learn anything,it takes some time for that memory to strengthen.And over the first 24 hours is actually where most of the forgetting happens.So that is where we wanted to intervene with caffeine and see if we can help reduce this forgetting." They took 160 caffeine-free people and showed them pictures of everyday objects. These people were asked if the objects could be found inside the house, or outdoors.Then some of the subjects were given a caffeine pill.The others were given a placebo--a pill containing nothing. 24 hours later,the subjects were shown the exact same images from the day before.They were also shown images with slight differences,and some completely new images. Both groups correctly identified the exact same and completely new pictures.But those who took the caffeine pill were better at spottingthe pictures that were slightly different. Professor Yassa says their answers helped to show the effects of caffeine on memory. And we find that if they are on caffeine they are much more likely to make the right decision." The amount of caffeine the researchers used in the study was similar to one cup of strong coffee.The researchers did not see any improvement to memory from smaller doses of caffeine or when it was given an hour before viewing the images.
Question: What is the focus of the text?
Options: (A) Caffeine can make people addicted. (B) Caffeine can make people energetic. (C) Caffeine can improve long--term memory. (D) Caffeine can make people feel comfortable.

Article: Dan Bebber is a senior research fellow at the University of Exeter in Britain. He says research has shown that wild plants and animals are moving toward Earth's North and South poles as the planet warms. Mr Bebber wanted to know if the same thing was happening with organisms that attack agricultural crops. He examined reports of first sightings of new insects and diseases around the world. The records came from CABI - the Centre for Agricultural Bioscience International. He says the group began collecting information from developing and industrialized countries years ago. Dan Bebber and his research team studied 612 different organisms - from viruses and bacteria to insects like beetles and butterflies. They found that since 1960, crop pests and diseases have been moving toward the poles at an average rate of about 3 kilometers each year. Mr Bebber says this puts the most productive farmland in the world in danger. "As new species of pests and diseases evolve and potentially the environment for them becomes more _ at higher latitudes, the pressure on the breadbaskets of the world is going to increase." Farmers face other threats. Invasive species passed through trade are also causing problems. Gene Kritsky is an Entomologist at the College of Mount St. Joseph in Ohio. He specialises in the study of insects. He says climate change may improve conditions for some invasive species. "It means that species in other parts of the world that might do well in warmer temperatures can now do well in the breadbasket of America." Another Entomologist Christian Krupke of Purdue University says the effects of these changes will depend very much on the crop, the insect and the disease. But he says the research is a warning sign that people should care about climate change and do something about it.
Question: The purpose of Dan Bebber's research was to find _ .
Options: (A) if farmland could be moved to colder places thanks to global warming (B) if diseases and insects harmful to crops were going towards colder areas (C) if organisms were moving to the north and south poles (D) if the number of crop pests was increasing

B
