When can design templates be applied to the presentation?

when you start
when you add a new slide
before you close the program
all of the above
none of the above

when you add a new slide

Explanation:

When creating a slide in a presentation you can add a different design template that might be different from the other templates used when creating previous slides.

You cannot add a new template to a presentation when you have already started the presentation that will be unethical practice and will end up confusing your audience and also adding a design template before the close of the program will be of no use and will not pass any information instead it will make your work to look disorganized at the end of the presentation.

there is no universally accepted definition of art. although commonly used to describe something of beauty, or a skill which produces an aesthetic result, there is no clear line in principle between (say) a unique piece of handmade sculpture, and a mass-produced but visually attractive item. we might say that art requires thought - some kind of creative impulse - but this raises more questions: for example, how much thought is required? if someone flings paint at a canvas, hoping by this action to create a work of art, does the result automatically constitute art?
