The question is based on the following passage. How Does Sound Travel? The music we hear, the angry shout from someone on the street, the call from our friends and other sounds near us travel before we could hear them. Those sound waves from those activities are transmitted through particles in mediums like: solids, liquids, or gases. These mediums are needed to be the vibrating objects in the sound. In the beginning, the sound waves move through each of these mediums by vibrating the molecules in the matter. The molecules in gases are well separated with no regular arrangement, in liquids they are close together with no regular arrangement and in solids they are tightly packed and usually in regular pattern. Next, different molecules arrangement influences the collision between particles. This collision is what mediates the propagation of sound. This is why the disturbance can also be said as another name of sound. Sound travels faster in the water than in the air because the molecules in the water are closely packed rather than in the air. Another factor in affecting on how the sound travels is the stiffness factor of the materials. The stronger the bond between the material's atoms, the more stiff it is, and hence, help propagate sound better. Thus, the speed of sound is greater in solid mediums as compared to gases and liquids. What will happen if a sound is made in an empty space which has an absence of medium?

Pembahasan

Soal menanyakan hal yang akan terjadi jika suara dibuat di ruang kosong yang tidak memiliki medium Pada paragraf pertama terdapat kalimat " Those sound waves from those activities are transmitted through particles in mediums like: solids, liquids, or gases. These mediums are needed to be the vibrating objects in the sound", yang artinya 'Gelombang bunyi dari aktivitas-aktivitas tersebut dirambatkan melalui partikel di dalam mediaseperti: benda padat, cair, atau gas. Media-media ini dibutuhkan untuk menjadi objek rambatan getaran bunyi.'. Berdasarkan kalimat tersebut, dapat diprediksi bahwa jika tidak ada media-media seperti yang telah disebutkan, tidak akan ada objek yang menjadi rambatan gelombang bunyi sehingga bunyi tidak bisa merambat ke mana pun. Jadi, pilihan jawaban yang tepat adalah Sound waves will not travel anywhere because there is no object to transfer the vibrations to yang artinya 'Gelombang suara tidak akan bergerak kemana-mana karena tidak ada objek untuk mentransfer getaran.'. Pilihan jawaban lainnyatidak tepat karena tidak sesuai dengan informasi yang ada pada teks. Pilihan A artinya 'Gelombang suara akan merambatpaling cepat karena tidak ada halangan.'. Pilihan B artinya 'Gelombang suara akan bergerak melalui molekul-molekul di ruang kosong tersebut.'. Pilihan C artinya 'Gelombang suara akan bergerak paling lambat karena sifat lingkungannya.'. Pilihan E artinya 'Gelombang suara akan dirambatkan melaluigetaran benda padat, cairan, atau gas sebelum telinga kita.'. Dengan demikian, pilihan jawaban yangtepat adalah D.
