Question 1
The diagram illustrates the process that is used to manufacture bricks for the building industry.
The provided diagram illustrates the brick manufacturing process utilized in the construction sector. The procedure consists of a total of seven phases, which commence with the excavation of clay and conclude with its delivery.
Initially, a sizable excavator is employed to extract the clay utilized in the production of the bricks. Following this, the clay is transferred to a metal matrix, where it is fragmented into smaller fragments. A roller facilitates this operation.
The clay is then combined with water and grit, and it is formed into bricks through the use of a wire cutter or by inserting the mixture into a mold. Following this, the bricks are dried in an oven for 24 to 48 hours.
Bricks undergo a searing and chilling procedure in the subsequent phase. They are heated in a kiln for two to three days at temperatures varying from 200 to 1300 degrees Celsius, before being cooled in a chamber. The pavers are subsequently packaged and transported to their final destinations.
Question 2
The process illustrated depicts the production of instant noodles. In its entirety, this artificial undertaking can be categorized into four primary phases: unprocessed ingredient storage, dried noodle assembly, preparation, and packaging for subsequent consumption.
The flour used to produce instant noodles is initially stored in silos. The flour, in conjunction with oil and water obtained from an additional source, is conveyed to the mixers, where it is rolled into dough sheets to initiate the assembly line procedures. The factory machinery is utilized to cut these sheets into strips, which are subsequently formed into compact “Noodles discs.” These discs are then sautéed in oil, allowed to dry, and finally positioned in containers alongside a variety of vegetables and seasonings.
In order to ensure that the final product is retail-ready, the last stage of preparation is to label and secure the contents.
Question 3
The method depicts how energy is created in a hydroelectric power plant. In general, the figure may be divided into day and night phases, with the daylight portions incorporating energy production from a river and water storage in a reservoir. During the night, the water flows backwards towards an original reservoir and the river.
The river is channeled into a high-level reservoir supported by a dam in the first step of the procedure. The intake area leading to the power station is open during the day and shuts off at night. During the day, water runs through the power station turbines to create energy, which is subsequently sent to a national grid via power lines, while the water flows to a low-level reservoir.
The reversible turbines that power the generator throughout the day enable the station to pump water from the low-level reservoir into the high-level reservoir for usage the following day.
Question 4
The figure depicts the evolution of ancient and contemporary horses, with specific attention on the construction of the feet. From a wide view, it is clear that as horses grew in size, their feet extended and expanded until they merged to form a characteristic hoof.
Eohippus, an ancient horse about 40 million years ago, is distinguished by its smaller body and paw with four thin phalanges. The Mesohippis evolved next (30 million years ago), with a bigger body more like today’s horse with three different fingers, the middle one being thicker and somewhat longer.
The Merychippus appeared 15 million years ago, distinguished by a bigger body and a longer middle digit. This eventually leads to the modern horse, which is the biggest in size, has a full mane, and the individual digits have combined into a single hoof capable of supporting a bigger frame.
Question 5
The graphic depicts the process of producing leather goods for retail sale. Overall, it is clear that there are three major phases to this wholly man-made process, starting with the initial delivery of raw material to the facility, followed by material preparation and processing, and lastly consumer product manufacture.
First, different animal leather skins are dried. Following that, they are transported by truck to a plant where they are cleaned in water and lime. The skins are then soaked in additional lime for a period of time before being flattened using a machine with huge rollers.
The skins are then flattened and steeped in tannin, which is made up of water and vegetable debris. They are then polished by another rolling mechanism and transported by trucks to another plant. The finished goods are made at this plant and sold in retail stores.
