What does "cursory" mean?

The term "cursory" refers to something that is done quickly and without paying much attention to detail. When a task or review is cursory, it implies that it is superficial and lacks thoroughness. Therefore, the correct answer indicates that a cursory examination or glance is one that is brief and may overlook important elements. This contrasts with an approach that is thorough and detailed, which would involve taking the time to ensure all aspects are considered carefully. The other options suggest states of being that imply a deliberate or careful approach, which does not align with the connotation of hastiness associated with "cursory."
