The present line graph provides the percentage of homes without internet access from 2008 to 2014, due to five main reasons.

Overall, lack of interest and skills, which were reported as the two most significant reasons, experienced a rising trend throughout the period. The other three factors, however, remained largely unchanged, almost returning to their initial values by the end of the period.

The more significant factors, lack of interest and skills both exhibited upward trends. In 2008, for instance, about 32% of homes found the internet not useful or interesting enough, a figure which rose at different rates to a peak of 60% in 2013. After this dramatic rise, the figures dropped steadily to about 52% in 2014. Lack of skills, on the other hand, experienced a similar rise between 2008 and 2010 (from about 14% to about 22%) yet remained unchanged until 2012, at which point it dropped to 20%, followed by a soaring of more than 10% and finishing at about 32%.

On the other hand, high equipment and access costs accounted for about 15% and 11% respectively, with different patterns until 2012, at which point they met at about 15% and remained mostly correlated for the rest of the period and by 2014, both declined to 12%.

Privacy and security were not reported as significant concerns. The corresponding figure for them exhibited imperceptible change, hitting a low of almost zero in 2013, after which concerns grew by about six percent by 2014.

The present diagram depicts the various stages involved in electricity generation using tidal power in an artificial lagoon. The water required to accomplish the process is supplied from the sea.

Overall, the process involves two main stages, during the second of which electricity is generated. In the first stage, water fills the lagoon, so that it can pass through the turbine in the second stage while exiting the structure.

In the high tide stage, water flows into the lagoon from the sea and through the open inflow gate. The water level rises to the high water mark in a twelve-hour process, during which time the outflow gate is closed, meaning no electricity is yet generated.

In the low tide stage, and once the water level has reached a maximum, the inflow gate is closed, and the outflow gate is opened instead. As water exits the lagoon, it passes through a turbine that is placed at the mouth of the outflow gate and generates electricity. Like the previous one, this stage, too, takes 12 hours.

The estuary levels correspond to the water level in the lagoon; that is, they are high during the first stage and low during the second.

The present diagram documents the volcanic eruption process through which the Hawaiian island chain in the Pacific Ocean has been created. The major islands in the chain are Niihau, Kauai, Oahu, Kolokai, Lanai, Kahoolawe, Maui, and Hawaii, the oldest of which was formed 80 million years ago.

Overall, the diagram indicates that each island is formed by several deep-see volcanic eruptions, which create mountain-like bulges in the pacific plate, causing the island to rise above the water surface. In addition, the imperceptible movement of the Pacific plate allows each set of eruptions to add a new island to the chain. A small map of the major islands in the chain is also included.

The volcanic eruption originates 2883 km below surface. During the eruption, as ‘hot spot’ spume remains trapped under the solid dense rock, magma spume pierces both the solid dense rock and the Pacific plate and shapes an island through repeated eruptions.

Meanwhile, the Pacific tectonic plate, on which the islands are located, shifts westward at a very slow speed of 7 to 9 cm per year. Over millions of years, this allows for the creation of several islands, collectively known as the Hawaiian island chain, with Hawaii as the largest island.

The present process diagram depicts the seven stages involved in an innovative electricity generation method, using methane fermented from household compost.

Overall, the process involves two stages, namely methane production and electricity generation. Methane is first captured, stored, and compressed; it is then burned to produce electricity. In this way, a home can meet a portion of its power needs in an environmentally friendly way and without paying for electricity from the grid.

In the first stage, capturing methane is accomplished by placing a steel tank in the ground and filling it up to 75% with compost, which includes leaves, food, and scraps. After water is added, the fermented methane from the mixture is captured and transferred to a storage via several pipes. Next, the gas is compressed, and then it is transferred to the electricity generation phase through a long pipe.

In the second stage, the gas is burned in the combustion engine, which releases mechanical energy. Next, the mechanical energy is transformed into electrical energy in a generator and transferred to a large battery, where it is stored. Finally, the electricity, which was being stored, is connected to the home’s electrical system.

Someland’s Main Exports

Free IELTS Writing Task 1 Sample Essay

The given bar chart compares the sales of Someland’s three main exports: International Tourism, Dairy, and Meat Products in 2005 and 2015 as well as projected production for 2025. The units are measured in billions of dollars USD.

Overall, each product showed a distinct trend in exports, and in each year, a different product enjoyed the highest sales. Meat product sales has exhibited a falling trend, for instance, while international tourism has been increasing, and both products are projected to continue their respective trends. On the other hand, Someland has managed to significantly boost Dairy export, yet projections indicate a slight decrease in 2025. In addition, in 2005 and 2015, international tourism and dairy products had the highest amounts of exports. In 2025, the former is projected to be the largest export among the three.

Among the three products, Dairy exports and International Tourism stayed above $4 billion throughout the period. In 2005, International Tourism (about $6 billion) surpassed Dairy (about $5 billion); however, despite the growth in the exports of both products in 2015, the sales of Dairy products exceeded international tourism by roughly more than a billion to become Someland’s main export, at just below $8 billion, as compared to roughly $7 billion for the former. Surprisingly, in 2025, the amount for international tourism is projected to gain its place back as the principle export, with just below $8 billion, while the figures for dairy products will be dropping to between $7 and $8 billion USD.

On the other hand, meat products generated a lower revenue of $4 billion in 2005 for Someland, which was the highest. From then on, the exports shrank in a steady downward trend to reach about $3.5 billion in 2015. The country’s meat exports are expected to follow this trend by 2025 and decline further to about $3 billion dollars, which is the lowest projection for that year among the three products.

The present graph provides information about the changes in the expenditure of four countries (Germany, France, Italy, and Austria) over a ten-year period, starting in 1995 and ending in 2005. The units are measured in million dollars USD.

            Overall, all four countries witnessed an upward trend with Germany as the highest spender throughout the period, followed by France. In addition, Austria had the most dramatic increase among the four countries, which allowed them to overtake Italy in 2003 and take the third place behind the French.

             From among the four nations, France and Austria experienced no decline in their spending. Book purchases in Austria started at $30 million in 1995, had a steady increase to $40 million by 1999, and leveled off from then on, until 2001. Austrian book purchases then saw a soaring of about $30 million and reached just above 70 in 2005. France, on the other hand, started at above $50 million and increased its spending steadily to about $75 million by the end.

            In contrast, Germany and Italy had some decline in their spending. The former started at $80 million and went up to $90 but dropped back to $85 by 2003. From then on, it surpassed its previous high point and reached $95 million by the end of the period. Italy saw its decline between 1997 and 1999 (from about $55 to $50 million) but had a very steady increase to just above $60 million by the end.
