Directions: Answer the given question based on the following passage:

For a creative writer, the most important part of the entire process from conception to fructification starts even before conception itself. Just as the human embryo needs a certain set of favorable circumstances before it can even begin to exist, the writer’s muse requires inspiration. Once inspiration strikes, and it can sometimes happen in the middle of sleep, the next step involves holding on to the idea lest it be lost in the rough house of everyday life. This process involves allowing the idea to ferment and hopefully turn into a culture that will deliver heady literary wine. The writer needs to let his subconscious work on the germ, knead it, tweak it, and evaluate it. Many ideas are stillborn, many more are worthy, and still the author fails to take them to the logical conclusion. Only a few survive the tumult and make it to the next stage which involves the channelizing of the idea towards the building up of an atom around the nucleus. While the author needs to nurture the idea, woe betides the one who gets too attached to it, especially if his livelihood depends on it. You might like to chew gum, but a cow will still prefer to chew the cud.
