Read the following passage and mark the letter A, B, C, or D to indicate the answer to each of the question

Vietnam’s population is ageing quickly. In 2017, more than 10 per cent of the population will be 60 and older, and in 15-20 years the elderly will account for one third of the total population. This raises concerns about healthcare, welfare and pensions for the elderly at a time when Vietnam is focusing on economic integration and requires a large labor force. So far two solutions have been proposed: to loosen the two-child policy and to increase the retirement age to 58 for women and 62 for men. By ending the two-child policy the government expects to make up for the ageing population within the next 20 years. But its effect could be creating an uncontrollable boom in the Vietnamese population. When the government loosened the two-child policy in 2015 in a trial period, in the first 6 months of 2016 the third child birth rate increased remarkably by 7.5 per cent

Raising the retirement age has been proposed by the Ministry of Labor pending parliamentary evaluation in May 2017. While the policy is beneficial in utilizing the work experience of the elderly while creating savings in the pension budget, it also means fewer job prospects and promotion opportunities for younger generations. It is also not in the interest of all the elderly, especially the 70 per cent of Vietnam's labor force working in manual labor-intensive sectors such as agriculture, manufacturing and construction where working above the age of 50 can be dangerous and unproductive. Despite these drawbacks, raising the retirement age is still considered by policymakers as one of the key solutions to the ageing population problem in Vietnam. However, these are only temporary solutions.

Nomophobia, short for "no-mobile-phone phobia," is a modern phenomenon that affects many people in today's digital age.

What is nomophobia? It is the irrational fear of being without one's mobile phone or being unable to use it. This condition can cause anxiety and distress, and it highlights the profound impact mobile devices have on our lives. The fear of losing or being separated from one's phone is a growing concern. Some common situations that trigger nomophobia include misplacing one's phone, running out of battery, or losing network signal. The fear intensifies when people imagine not having their phones to contact friends and family, access the internet, or use GPS for navigation.

Who easily suffers from nomophobia? Nomophobia is not limited to any age group and can affect individuals of all backgrounds. It often becomes evident when people experience panic or anxiety when they forget their phones at home or are unable to use them temporarily. Symptoms may include restlessness, rapid heartbeat, sweating, and a sense of insecurity.

The roots of nomophobia lie in the convenience and connectedness that mobile phones provide. These devices have become integral to our daily lives, serving as not just communication tools but also cameras, entertainment hubs, personal organizers, and more. This dependence on mobile phones can lead to a feeling of vulnerability when separated from them.

In which paragraph does the writer mention the fear of being without mobile phones?
