Ans: The line graph depicts the consumption trends of fast food among Indian urban teenagers from 2005 to 2020. The data reveals a steady increase in fast food consumption over the years, with a notable acceleration in the growth rate from around 2010 onwards. In 2005, the consumption level was relatively low, hovering around 15 units. However, by 2020, this figure had more than doubled, reaching approximately 35 units. The period between 2010 and 2020 saw a particularly steep rise, indicating a significant shift in dietary habits among Indian urban teenagers towards fast food options. This trend could be attributed to various factors such as increased availability of fast food outlets, changing lifestyles, and evolving food preferences influenced by globalization and urbanization. The data underscores the growing popularity of fast food among Indian urban teenagers over the past decade and highlights the need for attention to the potential health implications associated with excessive fast food consumption.

Ans:  The line graph presents the temperature changes over the course of a day in a specific city. From a glance at the graph, we can observe that the temperature rises gradually from the early hours of the morning, reaching a plateau of around 20°C between 12 noon and 3 pm. This plateau suggests a period of stable, warm temperatures during the middle of the day, which is a common pattern due to solar heating reaching its peak around these hours.
Following this peak, the temperature begins to decline, indicating that the effects of solar radiation are diminishing as the sun sets. The graph shows a steady decrease in temperature from 3 pm onwards, reaching its lowest point at midnight. This is typical of the diurnal cycle of temperature, where heat accumulates during the daylight hours and is then lost during the night when the absence of sunlight leads to cooling.
It's also worth noting that the lowest temperature recorded was at 6 am, which is often the coldest part of the day because it follows several hours of cooling throughout the night. The warmest part of the day does not immediately follow noon, which is when the sun is highest in the sky, but rather a few hours after, which could be due to the time it takes for the Earth to heat up.
From this data, one could conclude that the city experiences a moderate climate with no extreme temperatures recorded throughout the day. The temperatures remain within a comfortable range for most people, with a maximum of 20°C and a minimum just above 5°C. The temperature profile is typical for many regions of the world where there is a clear difference between day and night temperatures but without severe extremes.
