Read the paragraph and answer the question Nos. 13-18:

Adolescence is a period of rapid growth and development bridging childhood and adulthood. Practising healthy eating behaviour is one of the most important factors to meet the nutritional needs of adolescents. Proper eating behaviours that are learned in early life are maintained in adulthood thus reducing the risk of major chronic disease. Physical and psychological changes occurring during this period usually significantly influence their dietary behaviours. As teens become more independent, they make more of their own food choices. However, being influenced by a massive amount of factors (biological, social, physical, economic, psychological beliefs and knowledge about food) and changing of lifestyle may affect their dietary choices and eating behaviour, thus making them fail to adhere to healthy eating practices. Peer pressure in colleges leads adolescents to eat non-nutritional foods like pizzas and burgers. Due to irregular college schedules, intake of caffeinated drinks increases and water intake reduces. Poor nutrition can lead to reduced concentration in studies, low stamina, depression or poor posture.
