Hello. You forgot to put the text to which this question refers. The text is:

Learning to play the trumpet may appear rather simple. After all, there are only three keys and a mouthpiece, right? However, many musicians will attest to the challenge of learning how to play the trumpet well. Playing the trumpet musically comes from developing what is called the embouchure (ahm-boo-shoor). This is how the player’s mouth muscles make contact with the mouthpiece and inevitably produce pleasing sounds—not noise, but beautiful tones. Remember that there are only three keys on the trumpet, so they must be pressed in multiple combinations to change pitch. Together with the musician’s lip muscles, the keys help determine pitch and quality of sound.

Some teachers insist beginning students learn the best technique by first starting with “buzzing.” A vibrating sound is made by forcing air out of the lips while they are tightly pursed. It’s not as easy as it may sound. It should be practiced first without the horn. Try doing this while changing pitches up and down the scale, or “sing-buzzing” different tunes. From this simple beginning, a student then progresses to buzzing into the mouthpiece. After success with this drill, students learn to change pitches, and with much practice will develop a decent tone when they play their trumpet. Practice is key to playing the trumpet well, despite its seeming simplicity

Explanation:

In the text the author presents arguments about how musicians feel that playing a trumpet is a great challenge, because the structure of the bugle, refers to a strong difficulty to play and generate good and decent sounds.

In the two statements above, we can see how the author of the text justifies the arguments, first he shows how the musicians prove the difficulty and secondly, he shows how it takes technique and a combination of lips and fingers to produce pleasant sounds.

yes, it can be both.

its hard for me to see which word is supposed to be in bold. if i knew then i would be able to better.
