Read the passage and answer the questions that follow.
You might not think of plants as particularly talkative, but they can communicate surprisingly well with each other, especially when faced with danger. According to a recent study in the journal Frontiers in Plant Science, injured plants send out emergency signals to alert their neighbours to start building up their defenses against threats. The research began after a University of Delaware plant specialist agreed to mentor a 16-year-old named Connor Sweeney on a research project. The excited high school student got to work immediately, spending all his free time, including weekends and summer breaks, in the lab at the university.
He first had to grow plants, known as mustard weed, for use in experiments which is not actually as easy as it sounds. He placed the seeds in Petri dishes and test tubes filled with jelly to promote growth. The seeds generally germinated about six days later and began to change into delicate three-inch saplings with bright green leaves.
After the plants had grown to a sufficient size, Sweeney sliced a leaf in two places -copying an insect bite- to see how it would begin the repair process. The following day, the young researcher was surprised to find that while the injured plant remained unchanged, the roots of the neighbouring young mustard weed had grown considerably longer and even had sideways offshoots. Sweeney then repeated the experiment multiple times to check the findings. To his surprise the results were the same! To see what was making the roots grow in these different ways, the university scientists conducted further tests and discovered that the injured plants were releasing chemicals to warn their neighbours of the impending danger. They believe that the healthy plant was growing its roots to absorb more nutrients to strengthen its defenses. As a result, the two scientists began looking for compounds that plants make to increase growth. Sure enough, each time an injured plant sent out a warning, the neighbouring mustard weeds began producing and using plant growth hormones.
The researchers were not sure why the plants actually communicated with each other. But the evidence from their research suggested that there was something more to look into. The plants were clearly in communication, and although it was originally thought that plants were always in competition with each other, this now seems not to be the case, or at least the relationships between them is different to what we as humans see as competition. Although this was not the first study that has analysed plants 'talking' to one another, it was the first to recognise how they communicate. In previous studies done on trees, scientists discerned that when warned about a possible insect attack, nearby uninjured trees begin producing large amounts of bug-repelling chemicals to ward off the attack. These are amazing observations that seem almost fictional. The idea that the plants around us are in constant communication with each other and there needs to be further research to find out if different species of plant can communicate or to see if they 'speak different languages'.

A6 days
B2 days
COvernight
DImmediately

Read the passage and answer the questions that follow.
Travelling was always something Peter had wanted to do and as he got older he began to plan. He decided that he must leave his home in Asia to get a good sense of the world. He thought that he should probably try and visit each continent. He sat down in front of his laptop and listed the continents: Oceania, Asia, Europe, Africa, North America, South America, Antarctica. Some of the continents he knew, but he was shocked to see that the closest continent he could visit was Africa. He had thought that it was a long way away.
It looked like planning this would be fun. When he looked at different maps of the world it turned out that there were different quantities and names of the continents which confused him a lot. Before he continued he asked his father's advice about how many continents there were. His father told him that for them, in their schools, they were taught that there were 7 continents. And although some other countries taught that there were 6 or 5, and that he should stick to what he understood for this project of his.
For the purpose of travel, Peter decided that he would use the system he knew, and this meant he would have to visit 6 more continents. He looked at the maps of the world and decided that he could go and visit his uncle in Africa and then his sister and her family in Europe really easily. He took this idea to his father who agreed with him although he thought it would be simpler to go east to Oceania. Peter knew that this was just because Oceania was where his father had always wanted to go because his brother lived there.

Which continent was closet to where Peter lived?

AEurope
BAsia
CAfrica
DSouth America

Read the passage and answer the questions that follow.
'10 Downing Street' is the official abode and the office of the first Lord of the Treasury and hence the Prime Minister of the United Kingdom. The headquarters of Her Majesty's Government, it is situated on Downing Street in the City of Westminster, in London. Number 10 is perhaps the most famous address in the United Kingdom and one of the most widely recognised houses in the world. Almost three hundred years old, the building contains about one hundred rooms.
There is a private residence on the third floor and a kitchen in the basement. The other floors contain offices and numerous conference, reception, sitting and dining rooms where the Prime Minister works and meets with and entertains government ministers, national leaders and foreign dignitaries. There is an interior courtyard and behind, a terrace overlooking a half acre garden. Adjacent to St. James Park, Number 10 is near the Palace of Westminster, the Houses of Parliament, and the Buckingham Palace, the official London residence of the British Monarch.
Originally Number 10 consisted of three houses that were offered to Robert Walpole as he was given the office of first Lord of Treasury. There after Walpole commissioned William Kent to join the three houses together. It is this larger house that is today
known as 'Number 10 Downing Street. The arrangement was not an immediate success. Despite its size and convenient location near Parliament, only a few early Prime Ministers lived there. Costly to maintain, neglected, and run-down, Number 10 was close to being razed several times. Nevertheless, Number 10 survived and became linked with many statesmen and events in British history. In 1985, Prime Minister Margaret Thatcher said Number 10 had become "one of the most precious jewels in the national heritage".
How many rooms are there in '10 Downing Street'?

AThree hundred rooms
BA private residence
CAbout one hundred rooms
DNone of these
