Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. appears
- Appears is a suitable option.
- It refers to "seems" or "becomes visible," which is an excellent fit when talking about the genetic nature of bipolar disorder.
- Since it accurately expresses the concept that bipolar disorder often seems or is thought to be inherited.
- Compared to other options:
- "Signs": Although it is a noun, a verb is required here, therefore it would not make sense grammatically in this context.
- "Injects": It denotes putting something into another, which is inappropriate when talking about how a state is understood or experienced.
- "Pings": It is a phrase that is frequently used to refer to sending a signal; it is not appropriate to describe how bipolar disorder is understood in this context.
