প্রশ্নঃ Spray cans produce an aerosol ,which is ____.
বর্ণনাঃ Spray cans produce an aerosol, the technical term for a very fine spray. They do this by means of a pressurized propellant, which is a liquid that boils at everyday temperatures. Inside the can, a layer of gaseous pressure increased, and eventually, it becomes so high that boiling stops. When the nozzle is pressed, the gas pressure forces the product up the tube in the can and out of the nozzle in a spray or foam. The propellant may emerge as well but, now under less pressure, it immediately evaporates. First patented in the US in 1941, aerosol spray cans have been used as convenient packages for an ever-increasing range of products including paints, insecticides, and shaving cream to name a few. The can is filled with the product to be sprayed and the propellant, a compressed gas such as butane or Freon. The gas is partly liquefied by the pressure in the can, but there is a layer of free gas above the liquid. As the can empties liquefied gas vaporizes to fill the space.

প্রশ্নঃ It is essential that "commercial " fishing "has " large shoals of fish of one "species " "within" reach of markets.
বর্ণনাঃ Species এর Singular কিংবা Plural রূপ Species ই । তাই এর পূর্বে One থাকলেও Grammatically তা ঠিক আছে । আর Large shoals of fish of one species অর্থ এক প্রজাতির বড় এক ঝাঁক মাছ । কিন্তু বাক্যে Subjunctive verb হিসেবে Essential থাকার কারণে Subject যাই হোক না কেন Verb এর মূল রূপ বসবে । কাজেই Has না বসে Have হবে । এরকম কিছু Subjunctive verb হলোঃ Advise, ask, command, demand, insist, move, order, prefer, propose, recommend, require, request ইত্যাদি । বাক্যের অর্থঃ বাণিজ্যিক উদ্দেশ্যে মাছ ধরার ক্ষেত্রে এটা খুবই গুরুত্বপূর্ণ যে হাতের নাগালেই একই প্রজাতির বড় ঝাঁক মাছ থাকবে । The English subjunctive is a special, relatively rare verb form that expresses something desired or imagined. We use the subjunctive mainly when talking about events that are not certain to happen. For example, we use the subjunctive when talking about events that somebody: wants to happen. I wish it were real. (As this expresses a wish, was becomes were.) It is imperative that the game begin at once. (As this expresses a demand, begins becomes begin.) I propose he work full time.
