Explanation:
Time measurement is the ability to measure duration to complete a task. For example, time taken to reach from Jaipur to Delhi. In general, time is calculated using the formula distance travelled per unit time. Notice some examples below: As in "How long does it take us to complete a task", A question is asked seeking the duration of the task, so for that time-measurement is needed. In "When did an incident happen during the day", a question is asked seeking the time, so for that also time-measurement is needed. While in "When did an incident happen during the day", the amount of water displayed by a 3D object is represented by its volume. so, for that no time-measurement is needed. Hence, we conclude that the above statement talks about time measurement.
বাংলা সাহিত্য ও ব্যাকরণ হলো বাংলা ভাষার দুটি অবিচ্ছেদ্য অঙ্গ। বাংলা সাহিত্য হলো বাংলা ভাষায় রচিত কবিতা, উপন্যাস, নাটক, গল্পসহ সৃজনশীল ও মননশীল রচনার সমষ্টি, যার সূচনা দশম শতাব্দীতে 'চর্যাপদ' এর মাধ্যমে। অন্যদিকে, বাংলা ব্যাকরণ হলো এমন একটি শাস্ত্র বা বিজ্ঞান, যা বাংলা ভাষার গঠন, প্রকৃতি, ধ্বনি, শব্দ ও বাক্যের নিয়ম-কানুন বিশ্লেষণ করে ভাষার শুদ্ধ রূপ ও প্রয়োগ শেখায়।
