Read the following passage and answer the questions that follow-Parents all over Iceland’s capital Reykjavik embark on a two-hour evening walk around their neighbourhood every weekend, checking on youth hangouts as a 10 pm curfew approaches.The walk in Reykjavik is one step toward Iceland’s success into turning around a crisis in teenage drinking.Focusing on local participation and promoting more music and sports options for students, the island nation in the North Atlantic has dried up a teenage culture of drinking and smoking. Icelandic teenagers now have one of the lowest rates of substance abuse in Europe.The Icelandic Centre for Social Research and Analysis, the institute pioneering the project for the past two decades, says it currently advises 100 communities in 23 countries, from Finland to Chile, on cutting teenage substance abuse. “The key to success is to create healthy communities and by that get healthy individuals, ” said Inga Dora Sigfusdottir, a sociology professor who founded the Youth of Iceland programme, which now has rebranded as Planet Youth.The secret, she says, is to keep young people busy and parents engaged without talking much about drugs or alcohol. That stands in sharp contrast to other anti-abuse programmes which try to sway teenagers with school lectures and scary, disgusting ads showing smokers’ rotten lungs or eggs in a frying pan to represent an intoxicated brain.“Telling teenagers not to use drugs can backlash and actually get them curious to try them,” Ms Sigfusdottir said. In 1999, when thousands of teenagers would gather in Reykjavik every weekend, surveys showed 56% of Icelandic 16-year-olds drank alcohol and about as many had tried smoking.Years later, Iceland has the lowest rates for drinking and smoking among the 35 countries measured in the 2015 European School Survey Project on Alcohol and Other Drugs. On average, 80% of European 16-year-olds have tasted alcohol at least once, compared with 35% in Iceland, the only country where more than half of those students completely abstains from alcohol. Denmark, another wealthy Nordic country, has the highest rates of teenage drinking, along with Greece, Hungary and the Czech Republic, where 92% to 96% have consumed alcohol. In the US, teen drinking is a significant health concern, because many US teenagers are driving cars and do not have access to good public transport like teenagers in Europe. Reykjavik mayor Dagur B. Eggertsson said the Icelandic plan “is all about society giving better options” for teens than substance abuse. He believes the wide variety of opportunities that now keep students busy and inspired has dramatically altered the country’s youth culture. Local municipalities like Reykjavik have invested in sport halls, music schools and youth centres.To make the programmes widely available, parents are offered a 500 US dollarannual voucher toward sports or music programmes for their children.

Aanandi took two test tubes and marked them A and B. She put two spoonfuls of sugar solution in each of the test tubes. In test tube B, she added a spoonful of yeast. Then she attachedtwo incompletely inflated balloons to the mouth of each test tube. She kept the set-up in a warm place, away from sunlight. What do you predict will happen after 3-4 days ? She observed that the balloon attached to test tube B was inflated. What can be a possible explanation for this ?

Your Answer:

Water evaporated in test tube B and filled the balloon with the water vapour.
The warm atmosphere expanded the air inside the test tube B, which inflated the balloon.
Yeast produced a gas inside the test tube B which inflated the balloon.
Sugar reacted with warm air, which produced gas, eventually inflating the balloon
