Read this fictional request: "Could we use the small room on Tuesday evening? We expect eight people. Is there a projector, and may we bring refreshments?" Now read the reply: "The small room is available on Tuesday. It has a projector."
The reply answers availability and equipment, but it does not answer the refreshments question. It also does not clearly confirm the evening period or that a booking has been made. Those details need attention before treating the arrangement as complete.
Match answers to questions
Make a short list: date and period, group size, projector, refreshments, booking status. Mark each as answered, partly answered, or unanswered. This prevents a friendly reply from feeling more complete than its actual content.
Write a focused follow-up: "Thank you. Could you confirm that the room is available from six to eight in the evening, and whether refreshments are allowed? Please also let me know how to complete the booking."
Practice with a partner who deliberately leaves one question unanswered in each reply. Avoid accusing the writer of ignoring you; a missing answer may be accidental. The reading skill is to notice the gap accurately, and the writing skill is to request the remaining information without resending a long message that obscures the specific points still needed.
