2. where do you put a threaded bobbin and where does the thread from the bobbin go when the machine is in use?

Raise the needle to its highest position by rotating the hand wheel toward you. to the right. Bobbin cover will pop up sufficiently to allow you to remove the cover.Insert the bobbin making sure the bobbin rotates counter- clockwise when you pull the thread.NOTE: This is a very important step as the bobbin can become unthreaded and cause sewing problems if it rotates clockwise.Pull thread through the slot (A) and then to the left.With a finger held gently on top of the bobbin, pull the thread until it stops in slot (B). Then pull about 6" (15 cm) of thread and lead it towards back of the machine under the presser foot.NOTE: This is also a very important step to assure the bobbin thread does not slip out of position.Replace the bobbin cover plate onto the needle plate.

Iwould go with write exactly two extra paragraphs to point out additional information. but the keyword "exactly" throws me off. leads me to believe it's d. go with your gut feeling. either "write exactly two extra paragraphs" or "none of these".

Idon’t know can you give me background information
