Question

1. below are the outfits that 4 different students arrived in lab wearing. who is dressed the most appropriately?

student a: long sleeves, slides, dangly jewelry
student b: pants, sneakers, and hair tied back
student c: lab apron, shorts, hair pulled halfback
student d: fringed vest, flip flops, hair down

Explanation:

In a lab setting, appropriate attire includes closed - toed shoes (sneakers are closed - toed), pants (to protect legs), and tied - back hair (to prevent it from interfering with lab work or catching fire/coming in contact with chemicals). Student A has slides (open - toed, unsafe) and dangly jewelry (can get caught or contaminate). Student C has shorts (expose legs to potential hazards) and hair only pulled half - back (not fully secured). Student D has flip flops (open - toed) and hair down (unsecured), and a fringed vest (loose fabric can be a hazard). So Student B’s attire is most appropriate.

Answer:

B. Student B: Pants, sneakers, and hair tied back
