The question is based on the following text. To make or manufacture Biodiesel, you must first prepare the raw materials. The raw materials needed in the production of Biodiesel are a small amount of methanol and a ready supply of vegetable product. ( ____ ) The oil is then turned into biodiesel through a process called ester interchange. To complete this process, the vegetable oil has to be combined with a smaller amount of methanol and then put in the presence of a small quantity of an alkaline catalyst (for example, 5% to 1% sodium hydroxide). Vegetable oil is made up of so-called triglycerides, which is a compound of the trivalent alcohol glycerin with three fatty acids. The goal of ester interchange is to separate the glycerin molecule from the three fatty acids and replace it with three methanol molecules. This process then yields roughly 90% Biodiesel and 10% of a glycerin byproduct. The glycerin byproduct can be used in a number of other chemical processes for different industries. The correct sentence to fill in the blank and make a meaningful paragraph is ...

Pembahasan
Untuk membuat paragraf yang koheren dan bermakna, harus ada hubungan keterkaitan antara kalimat. Maknanya, bagian rumpang (kalimat ke-3) harus bisa menjembatani ide antara kalimat ke 2 dan kalimat ke-4. Subject pada kalimat setelah bagian rumpang adalah ‘The oil..’ terjemahannya ‘minyak tersebut’. Sementara, 2 kalimat sebelum kalimat rumpang tidak ada yang mencantumkan apapun tentang minyak sama sekali. Justru yang disebutkan adalah tentang ‘vegetable product’ (produk nabati - nabati berarti produk tetumbuhan seperti daun, kacang, biji, umbi) Berarti minyak yang disebutkan di kalimat ke 4 adalah minyak yang terbuat dari produk nabati (minyak dari tumbuhan mentah) atau bahasa inggrisnya adalah vegetable oil. Jadi, jawaban yang tepat adalah A.
