Rh in the context of the criminal code, a reasonable observer would “expect the term ‘drew blood’ to describe a violent act,” Manning 2461. Common sense similarly bears on judgments like whether a floating home is a “vessel,” Lozman v. Riviera Beach, 568 U. S. 115, 120–121 (2013), whether tomatoes are “vegetables,” Nix v. Hedden, 149 U. S. 304, 306–307 (1893), and whether a skin irritant is a “chemical weapon,” Bond, 572 U. S., at 860–862.

Why is any of this relevant to the major questions doctrine? Because context is also relevant to interpreting the scope of a delegation. Think about agency law, which is all about delegations. When an agent acts on behalf of a principal, she “has actual authority to take action designated or implied in the principal’s manifestations to the agent … as the agent reasonably understands [those] manifestations.” Restatement (Third) of Agency §2.02(1) (2005). Whether an agent’s understanding is reasonable depends on “[t]he context in which the principal and agent interact,” including their “[p]rior dealings,” industry “customs and usages,” and “the nature of the principal’s business or the principal’s personal situation.” Id., §2.02, Comment e (emphasis added). With that in mind, imagine that a grocer instructs a clerk to “go to the orchard and buy apples for the store.” Though this grant of apple-purchasing authority sounds unqualified, a reasonable clerk would know that there are limits. For example, if the grocer usually keeps 200 apples on hand, the clerk does not have actual authority to buy 1,000—the grocer would have spoken more directly if she meant to authorize such an out-of-the-ordinary purchase. A clerk who disregards context and stretches the words to their fullest will not have a job for long.

This is consistent with how we communicate conversationally. Consider a parent who hires a babysitter to watch her young children over the weekend. As she walks out the door, the parent hands the babysitter her credit card and says: “Make sure the kids have fun.” Emboldened, the
