Some people say that man's desire for war is due to his fight for survival and that war is necessary to preserve his virility. Yet, war nowadays leaves a legacy of the weakest men and stimulates not the noble but the bestial qualities of mankind.
 A venture of some kind is necessary for man; he will inevitably deteriorate physically and mentally if his life is one of ease and luxury lived in an atmosphere of ‘Safety First.’ This is the real reason behind our love of sports in the open air. It is no use being a millionaire if one suffers from chronic in digestion; a tramp with good innards is far happier. Nothing that money can buy is worthwhile without good health. There is no better way to perfect health and physical fitness than to walk over or climb hills and mountains.
 But mountains give us much more than mere physical fitness; they exercise the mental faculties as well. Climbing a high and difficult peak is as much a mental exercise as a physical exercise. It calls for sense and judgement for planning and thinking ahead, for anticipating difficulty and danger, for responsibility towards one's companions, and best of all, it brings the mountaineer into touch with the beauties of the universe. 

What is the best advantage mountaineering brings to an adventurer?  

Read the following passage and answer the questions given after it.

Tens of thousands of people who lost their homes in a catastrophic earthquake huddled around campfires in the bitter cold and clamoured for food and water on Thursday, three days after the temblor hit Turkey and Syria and killed more than 19,300 on Monday, 6th February, 2023.

Emergency crews used pick axes, shovels and jackhammers to dig through twisted metal and concrete - and occasionally still pulled out survivors. In the Turkish city of Antakya, dozens scrambled for aid in front of a truck distributing children's coats and other supplies. Many of those who lost their homes found shelter in tents, stadiums and other temporary accommodation, but others slept outdoors. In Antakya, over 100 bodies were awaiting identification in a makeshift morgue outside a hospital.

Authorities called off search-and-rescue operations in the cities of Kilis and Sanliurfa, where destruction was not as severe as in other impacted regions. The U.N. is authorised to deliver aid through only one border crossing, and road damage has prevented that thus far. U.N. Officials pleaded for humanitarian concerns to take precedence over wartime politics.

The scale of loss and suffering remained massive. Turkish authorities said on Thursday that the death toll had risen to more than 16,100 in the country, with more than 64,000 injured. In Syria, which includes government-held and rebel-held areas, more than 3,100 have been reported dead and more than 5,000 injured.

Rescue teams urged quiet in the hope of hearing stifled pleas for help, and the Syrian paramedic group known as the White Helmets noted that every second could mean saving a life. But more and more often, the teams pulled out dead bodies.

It was not clear how many people were still unaccounted for in both countries. Turkey's disaster-management agency said more than 110,000 rescue personnel were now taking part in the effort and more than 5,500 vehicles, including tractors, cranes, bulldozers and excavators had been shipped.

The Foreign Ministry said 95 countries have offered help. More than half of that number have sent a total of nearly 6,500 rescuers. Another 2,400 more are still expected to arrive. International aid for Syria was far more sparse.

Efforts there have been hampered by the civil war and the isolation of the rebel-held region along the border that is surrounded by Russia-backed government forces.

How many foreign rescue workers are engaged in the rescue work?
