Contrasting facts can be presented side by side.
The idea
Use whereas or while to link clauses with a subject and verb. Either clause can come first; use a comma between the contrasting clauses.
Examples
- Maya likes busy cafés, whereas Leo prefers quiet libraries.
- The northern path is steep, while the southern path is almost flat.
- Whereas the first design uses wood, the second uses recycled metal.
- Our old printer was noisy, whereas its replacement is nearly silent.
- While the museum is free on Sundays, the aquarium charges admission.
- Ari works best in the morning, while Sam is more focused at night.

Watch out
Do not assume while always means contrast: it can also mean that events happen at the same time. Context makes the meaning clear.
Try it yourself
Choose every option that expresses contrast. The coast is dry, ___ the mountains receive plenty of rain. (whereas / while / because)
Show answer or example answer
whereas / while
whereas and while both contrast the dry coast with the rainy mountains.
Choose every option that expresses contrast. ___ the blue bag is light, the red one is heavy. (While / Because)
Show answer or example answer
While
While introduces the contrast between the two bags; because would give a reason.
Choose every option that expresses contrast. The first room has windows, ___ the second has none. (whereas / despite)
Show answer or example answer
whereas
whereas joins two clauses; despite cannot directly introduce the complete clause here.
