Explanation:

The word "beleaguered" comes from a military term where it originally referred to a city or fortress being surrounded and besieged by enemy forces. Over time, its meaning has expanded to describe any situation where someone is being persistently troubled or harassed from all sides.

So when someone is described as beleaguered, it means they are under a lot of stress or facing multiple difficulties. For example, a company facing constant financial problems, legal issues, and negative press might be described as beleaguered.

Explanation: "Exemption" means being free from a duty or responsibility, which contrasts with "liability," which refers to being responsible or obligated. Liability refers to a legal or moral responsibility or obligation. In the context of employment, it means the duty or responsibility an employee has towards their job or organization. Exemption is the opposite of liability. It means being freed from a duty or obligation. If someone is exempt from something, they are not required to fulfill that particular responsibility. So, if "liability" describes a state of being obligated or responsible, "exemption" describes a state of being free from those obligations. For example, if an employee has a liability to their office, they are responsible for their work. If they have an exemption, they are not held to that responsibility.

Explanation: The choice of preposition in this context is important because it correctly conveys the relationship between Ravi and the cousin. "Married to" is the standard expression used to indicate that someone is in a marital relationship with another person. It shows the connection between the married individual and their spouse. For example, "Ravi is married to a cousin of mine" means that Ravi's spouse is a cousin of the speaker. "Married with" is not correct in this context because "with" does not convey the intended meaning of being in a marital relationship. "Married along with" is incorrect because "along with" implies accompaniment or addition rather than a marital relationship. "Married off" is not appropriate here because "married off" typically means to arrange for someone to marry, usually by someone else. So, "married to" accurately describes the relationship Ravi has with his spouse
