These children are now even more vulnerable to family separation, exploitation, and abuse. As buildings are deemed unsafe, they also are unable to return to school.

“In northern Syria, in particular, the threats to children from abuse were already extreme. The soaring poverty, within a warzone, now devastated by earthquakes, has created an unimaginable number of challenges, and suffering for children,” says Johan, director of the Syria crisis response in Amman, Jordan. “This earthquake has created the perfect environment for a health crisis -fueled by reduced healthcare capacity and disease (35)_____.”

Read the following passage about the Koromi trend and mark the letter A, B, C, or D on your answer sheet to indicate the best answer to each of the following questions from 31 to 40.

[I]. If you’ve done any traveling at all, you’re likely quite aware that customs and etiquette differ from one culture to another: what may be perfectly innocuous in one place may be hideously offensive in another, and vice-versa. [II]. Granted, even if you haven’t traveled at all, you’re probably aware of the fact that certain types of behavior aren’t exactly acceptable in other countries: belching at the table may be a sign of gratitude in some places, but in most areas of North America and Europe, such a display will earn you a fair bit of ire. [III]. Whether you plan on traveling to any of the places listed below or just doing business with a foreign client, it’s important to educate yourself on the standards of politesse and etiquette beforehand-the last thing you want to do is offend someone with any ignorant, boorish behavior. [IV]. Here’s how to be polite in different countries.

When dealing with Japanese clients, be sure to dress fairly conservatively, and make sure that you bow lower than they do upon meeting them. Accept gifts with both hands and open them later, not in front of the giver, and never blow your nose at the dining table. Avoid asking and answering direct questions: it’s better to imply rather than ask, and to answer with vagueness during conversations.

In Kenya, when greeting someone older or of a higher status than yourself, grip their right wrist with your left hand while shaking it; it’s a sign of respect and deference. Do ask questions about their health, family, business etc. before getting to major topics, as skipping these niceties is seen as impolite. If sharing meals, do not begin eating until the eldest male has been served and starts to eat.

Turning down an alcoholic drink is considered terribly offensive in Russia, so it’s a good idea to fortify yourself with some greasy food before heading out for a meal with Russian or Ukrainian clients. Don’t smile at strangers or they’ll think you’re deranged, and when paying for items, place your money on the counter rather than trying to hand it directly to the cashier.

Read the following passage about human life expectancy and mark the letter A, B, C or D on your answer sheet to indicate the best answer to each of the following questions from 23 to 30.

In the UK, comprising England, Scotland, Wales, and Northern Ireland, jokes and tricks can be played until noon on 1 April. After midday it's considered bad luck to play a trick. Anyone who forgets this and tries a joke in the afternoon becomes an 'April Fool' themselves.

So, what kind of jokes do people play? Well, a simple example would be telling your friend that their shoelaces are undone. Then, when they bend down to do them up, you shout, 'April Fool!', and they realise their shoelaces are fine.

Maybe it's not your kind of humour, but watch out, there's always someone who will find it funny! In Ireland, a popular prank is to send someone on a 'fool's errand'. The victim is sent to deliver a letter, supposedly asking for help. When the person receives the letter, they open it, read it and tell the poor messenger that they will have to take the letter to another person. This continues and the victim ends up taking the message to several different people until someone feels sorry for them and shows them what the letter says: 'Send the fool to someone else.'

In France, Belgium, the Netherlands (or Holland), Italy and French-speaking areas of Canada and Switzerland, the 1 April tradition is known as the “April Fish”. A common joke is to try to stick a paper fish onto a victim's back without being noticed.
