Whether it's the melodic sound of an Eric Clapton solo or the growl of a heavy metal band, the electric guitar has influenced popular music and culture more than any other instrument. Rock's greatest musicians have always been closely identified with their guitars. But instruments being designed for tomorrow's pop stars may look and sound rather different from today's familiar electric and acoustic guitars. Since the time when the electric guitar was invented, there have been incredible changes to the technical design of the instrument. From what was once a rounded wooden box with a hole in the front, the guitar has evolved into the smooth solid body of the rock guitarist's 'axe'. The most modern guitars are really computercontrolled synthesizers. Adolph Rickebacker's Electro String Company produced the world's first electric guitar. It was made of wood and played on the user's lap. The first real breakthrough in design came in 1950 when Leo Fender, a Californian radio repairman, made the first solid-bodied electric guitar, the Fender Telecaster. Soon after the inventor Les Paul made the famous Gibson Les Paul. Fender launched its stylish Stratocaster two years later. The guitars became standard instruments against which newer guitar designs are measured. All sorts of dift:erent materials have been used to make guitars. Acoustic guitars are made from wood, which gives a soft tone. Wood is also a popular material in electric guitar manufacture, but more modern materials such as glass and carbon fiber are also used. There have also been guitars with metal bodies and necks though these were never popular with players, who claim metal feels cold in the hand. Plastics, on the other hand, have been more used in guitar bodies. A company that makes parts for the aerospace industry has begun to use a kind of fiberglass that was originally used in helicopter blades to make the bodies for its electric-acoustic instruments. As long as scientists and musicians work together harmoniously, the electric guitar will continue to benefit from technological innovations. But for all the efforts of the guitar companies' design engineers, production managers and quality controller, it's the musicians who finally make the instruments sing- and not necessarily in the way the guitar maker intended. From the text we may conclude that ... (A) wood remains the best material for making guitars (B) guitar materials control the type of music the musicians play (C) technology has played a significant role in the design and development of guitars (D) today's designs are not very much different from those of the past (E) the use of fiberglass in aeroplanes was inspired by guitar makers

The word gambut (peat) is taken from the name of a village, Desa Gambut (now Garnbut sub-district), which is located about 10 km east of Banjarmasin, South Kalimantan. It is at this place that for the first time, rice has been successfully cultivated in peat soiled rice fields. In the soil taxonomy system, peat soils are grouped into a separate soil order called hisiosols, which means that the land is predominantly composed of organic soil materials in the form of remains of plant tissues. The nature and the characteristics of peat soils can be determined based on their physical and chemical properties. Gambut has dark brown to blackish colors. Although its basic materials are gray, brown or reddish, after decomposition, the dark humid compounds will appear. Furthermore, based on the weight of the contents, peat soil or gambut, which has undergone further decomposition, has a content weight ranging from 0.2 to 0 3 g cm2. Due to the low content weight, peat has a large capacity-as water storage about 2-4 times its dry weight. In fact, moss peat that has not decomposed can store up to 12 or 15 even 20 times more water than its own weight. In addition, peat soil has a large absorption area, which is up to 4 times greater than montmorillonite clay. Next, peat soil has acidic reaction properties. Decomposition of organic matters will produce organic acids that accumulate in the bodv of the soil hence increasing the acidity of the peat soil. Generally, peat soil shows real resistance to changes in pH when compared to mineral soils. As a result, peat soil requires more limestone to increase the pH at the same level of the value of mineral soil. Thus, peat soil requires a higher dose of fertilizers than mineral soil. Furthermore, based on the nutrients contained in it, peal soil is a type of nutrient-poor soil. High levels of N and organic matters in peat soils are also accompanied by a high N nitrification process so that the activity of heterotrophic organisms is not well stimulated and the organisms active in the nitrification process can carry out (heir activities. Therefore, the levels of P (phosphorus) and K (potassium) of peat soils are generally lower than that of the mineral soils. Also, the plants cultivated on the peat soil are very responsive to the fertilization using P and K. (adapted fiom hilps://freelearningji.wordpress.com} The phrase * large capacity as water storage* in paragraph 2 can be replaced by ... A. Power to withstand heavy water currents B. Capacity to keep water flowing stable C. High quality and quantity of water D. Potential to make large water storage E. Ability to deposit a large amount of water
