IELTS Writing Task 1: Line graph - Sample 2

Sample answer 1:

The provided line graph illustrates the acid level in the mouth which is created by consuming sweet foods specifically sugar and honey and possibility of tooth decay because of this acid level. As is presented in the line-graph, the higher the acid level the lower the pH value and a pH level less than 5.5 is detrimental for the tooth and causes the tooth decay.

The given graph shows that the initial pH level of our mouth is 7 which begin to fall after consuming sweet foods. When we eat sweet item like cane sugar, the pH level drops to 3.5 in 5 minutes and remain in danger level (below pH level 5.5) for more than 30 minutes. Consuming fruit sugar drops the pH level nearly to 4 and remains in danger level for about 20 minutes. And finally, when we eat honey, the pH level falls below 5 and it remains under risk level for about 13 minutes. As the low pH level means higher acidity and causes tooth decay, cane sugar among the mentioned three food items is the most harmful for our tooth.

Sample Answer 2:

The provided line graph shows the acid level of our mouth which is created by the consumption of fruit sugar, cane sugar & honey and compares their effects on our tooth decay.

When the pH level in the mouth is above 5.5, acidity remains in such a level that teeth are unlikely to be in danger from decay. Sweet foods, however, cause pH in the mouth to drop for a time, and the longer the pH levels remain below 5.5, the greater the possibility for decay to occur. The illustration compares the fruit sugar, cane sugar and honey, which are the most common ingredients of sweet foods, causes the pH level to drop below the danger level after 5 minutes.

Among these 3 sweet items, cane sugar decreases the pH level most quickly and causes to remain the level under the danger level for the longest period (over 30 minutes) and thus produce the greatest risk among the three. After consuming the cane sugar, the pH level drops to level 3.5 and remains there for over half an hour. On the other hand, fruit sugar causes the acidity level of mouth to fall under pH level 4 in 5 minutes and remains under threat level for 20 minutes. Finally, the honey appears to be less risky among the three causes the pH level to drop to 4.7 in 5 minutes and proceed to above pH 5.5 level within 15 minutes of consumption.

In conclusion, all of the sweet items possess the possibility of causing tooth decay and honey and fruit sugar are likely to cause less decay than the cane sugar does.

Tips for answering this Writing Task 1 Question:

1. Please note that the question asks you to "describe the information presented in the graph and also discuss the implications for dental health". So you have to mention which food item creates the highest acid level for a longer time and are comparatively injurious for our teeth. You must classify which food items are comparatively safe as well. First, compare the three food items in terms of the acid level they create in our mouth and how long this acid level remains in danger level. Then suggest which food items among cane sugar, fruit sugar and honey are comparatively safer and which item/ items are not.

2. Notice the following trends from the given line graphs:

a) Higher the acid level, the lower the pH level.

b) pH level below 5.5 is dangerous for the tooth as the tooth decay occurs below 5.5 pH level.

c) Honey is comparatively safer than other two food items as it decreases the pH level of the mouth slowly and the acid level goes to the safe level very quickly. On the other hand, after consuming cane sugar the pH level falls under danger level quickly and remains there for the longest time among the three food items.

3. To answer this question first mention the acid/ pH level which occurs the tooth decay and the level when it is safe. Now take the three given food items and mention them individually: how longer it takes to reach the pH level of mouth below 5.5 after consuming this food item and then how longer this level remains under 5.5. Finally suggest which food items are comparatively safer and which are not.

Summary of the Line Graph:

After consuming different sweet food items, the acid level of our mouth increases. The higher acid level is presented by the lower pH value. When the pH value gets under 5.5, the tooth decay occurs. Among the given three food items i.e. cane sugar, fruit sugar and honey, the third item (honey) is comparatively safer for our dental health. This is because after consuming all the honey the pH level remains under danger level for about 12 minutes compared to the 20 minutes for the fruit sugar and 31 minutes for cane sugar. This also indicates that the cane sugar is more likely to damage our tooth among the provided three sweet food items.

Sample Answer 3:

The bar graph illustrates the acid level of mouth after consumption of three different nutrients such as fruit sugar, cane sugar and honey over the period of forty minutes. According to the bar graph, it is obvious that cane sugar is the most acidic nutrient.

After the consumption of cane sugar, acidity level of mount increased sharply in five minutes and reached 3.5 pH level. From now onwards acidity level of mouth decreases steadily and reached the normal level after thirty-five minutes. However, teeth remained in dangerous level more than 25 minutes.

Another acidic nutrient is fruit sugar. After the consumption, the pH level of mouth decreased hurriedly and reached 4.25 in five minutes. After that, the level of acidity of month reached a normal level in 15 minutes. Therefore, teeth remained in dangerous level for 15 minutes. The last and the least acidic nutrient is honey, after the consumption of honey acidity level of mouth increased dramatically in five minutes and reached 5 pH level and then, plateau for 5 minutes and from now onward decreased moderately. However, teeth remained in an acidic environment for 10 minutes.

To conclude, the more hazardous nutrient for teeth is cane sugar because teeth remained in an acidic environment for more than 25 minutes.

Sample Answer 4:

The given line graph gives information on the amount of acid produced in our mouth by eating sugar and honey made from three different resources namely fruit, sugarcane and honey. Also, the graph estimates the time taken by them to reach different acid levels which are related to the tooth decay.

The maximum level of acidity produced by sugar content is reached 5 minutes after consuming them reaching up to 3.5 pH for sugarcane, 4 pH for fruit sugar and 5 pH for honey. After this time the acidity level declines for cane and fruit sugar, whereas it is sustained for 10 minutes for honey. Honey takes approximately 15 minutes to reach the pH of 5.5. It is at this pH at which tooth decay is unlikely. Fruit sugar takes 20 minutes and cane sugar takes the maximum time to reach this safety level. After 40 minutes all three sugars reach neutral pH that is 7.

Acidity promotes tooth decay which results in teeth cavities. Proper brushing and mouth washing can eliminate sugar particles and may protect teeth from the hazards of high acid levels.

From the given data it is clear that cane sugar has highest acidity and its acid content above safety level is sustained for the longest period in our mouth. Therefore it should be avoided. Honey is the safest sugary food which causes least chances of tooth decay.
