ques[1] = "Bacteria are not living organisms because they do not have a nucleus. Is this true or false?"
cor[1] =2
ans[1][1]="True."
ans[1][2]="False."
ans[1][3]="Not sure."
fb[1][1]="Sorry that's not correct. Even though they do not have a nucleus, bacteria can still grow, reproduce, move and respire. These are all features of living organisms."
fb[1][2]="Correct. Bacteria have their DNA loosely coiled in their cytoplasm. They are definitely living organisms."
fb[1][3]="Oh dear. Even though they do not have a nucleus, bacteria can still grow, reproduce, move and respire. These are all features of living organisms."


ques[2] = "Rod-shaped bacteria cause which one of these infections?"
cor[2] =3
ans[2][1]="Cholera."
ans[2][2]="Sore throat."
ans[2][3]="Food poisoning."
fb[2][1]="No, that's not right. The crescent moon 'vibrio' bacteria cause cholera."
fb[2][2]="Sore throats are caused by ball-shaped bacteria called streptococcus."
fb[2][3]="Yes, that's right. E. Coli and Salmonella are rod-shaped bacteria that cause food poisoning."


ques[3] = "What is the cause of ringworm?"
cor[3] =1
ans[3][1]="A skin infection by a fungus."
ans[3][2]="A worm growing under the skin."
ans[3][3]="Damage caused by a skin burn"
fb[3][1]="That's right. A fungus infects the skin and grows outwards. It produces a reddened circle on the skin."
fb[3][2]="No, that's not right. Ringworm is an old name from when people did not understand the infection. It is not caused by a worm."
fb[3][3]="Burns will cause skin damage but no a ringworm infection."


ques[4] = "How do viruses reproduce?"
cor[4] =2
ans[4][1]="They split into two by asexual reproduction."
ans[4][2]="They invade cells and direct the cell to make new viruses."
ans[4][3]="They can reproduce inside cells and asexually outside cells."
fb[4][1]="Bad luck. Other microbes, such as bacteria, can grow like this. Viruses cannot."
fb[4][2]="Excellent. They are only able to reproduce using a host cell's cytoplasm."
fb[4][3]="Sorry but that's not right. Viruses cannot reproduce outside of a host cell."


ques[5] = "What type of organism is an amoeba?"
cor[5] =1
ans[5][1]="Protozoa."
ans[5][2]="Bacteria."
ans[5][3]="Fungus"
fb[5][1]="That's right. Amoeba is a type of protozoa that can cause dysentery."
fb[5][2]="Bad luck. Amoeba is actually a protozoa that can cause dysentery."
fb[5][3]="No. Amoeba is a protozoa that causes dysentery."

ques[6] = "How do researchers think the SARS virus appeared?"
cor[6] =2
ans[6][1]="It has always been in the environment, it just spread to humans."
ans[6][2]="A mutation changed a virus living in chickens or domestic animals into the SARS virus."
ans[6][3]="The SARS virus arrived from space on cosmic dust."
fb[6][1]="That's a possibility but scintists think that new viruses appear due to regular mutations."
fb[6][2]="Yes, new viruses appear due to mutations. They often start in domestic animals and then spread to humans."
fb[6][3]="This is not as outrageous as it sounds. Some people believe material from space contains viruses. However, with SARS, the evidence points to a mutation in domestic animals."

ques[7] = "Why is candida known as an 'opportunistic' infection?"
cor[7] =3
ans[7][1]="It is easily passed from one person to the next."
ans[7][2]="It can only cause an infection after another infection has damaged the skin."
ans[7][3]="It causes infections when a person's normal immune defences are reduced."
fb[7][1]="Not really. Candida is quite often found on the skin. Normally it does not cause a problem."
fb[7][2]="This is nearly right but candida does not require another infection."
fb[7][3]="That's right. The person's defences need to be reduced for the candida to get established. This could be due to some other infection. However, it can also happen with medicines to suppress the immune system, antibiotics which kill 'friendly' bacteria or in a person suffering from HIV/Aids."

ques[8] = "How are outbreaks of bacterial meningitis treated?"
cor[8] =2
ans[8][1]="Antibiotics."
ans[8][2]="Antibiotics and vaccination."
ans[8][3]="Vaccination."
fb[8][1]="Antibiotics can treat the meningitis and may be given to close contacts who may be infected. However, they may not stop the spread of the disease."
fb[8][2]="Well done. Antibiotics can treat any infected people while vaccination will help to stop the infection spreading."
fb[8][3]="Vaccinations are used to prevent the infection spreading. Any infected people will need to be given antibiotics as well."

ques[9] = "How is malaria spread?"
cor[9] =3
ans[9][1]="In droplets when people cough or sneeze."
ans[9][2]="By direct contact with an infected person's skin."
ans[9][3]="When a person is bitten by an infected mosquito."
fb[9][1]="Sorry but malaria is not spread by coughs."
fb[9][2]="Malaria can't be spread just by touching an infected person."
fb[9][3]="Excellent. The mosquito transfers infected blood from one person to the next to spread the malaria."

ques[10] = "How many deaths world wide are due to malaria?"
cor[10] =1
ans[10][1]="2 million."
ans[10][2]="450,000."
ans[10][3]="40,000"
fb[10][1]="Yes, malaria is a major killer in Africa, Asia, Central and South America."
fb[10][2]="This is a massive number of people equivalent to the population of a large city. However, malaria kills a lot more."
fb[10][3]="This is the number of people in a large football stadium but malaria is much more deadly."
