Hi! A saiga is a kind of antelope with a special nose.
Original sentence: A saiga’s nose warms the air and traps sand dust.
That sentence is almost correct, but the words “sand dust” sound awkward. We usually say “sand and dust” (two things joined by and) or use the phrase “sand particles” or “dust from the sand.”
Better versions you can use:
- A saiga’s nose warms the air and traps sand and dust.
- A saiga’s nose warms the air and traps sand particles.
- Short and simple: A saiga’s nose warms the air and catches sand.
Why change it? When you talk about two things, like sand and dust, put the word and between them so it sounds right.
Great job noticing the sentence—keep asking questions!
