Which view of MS PowerPoint displays all the slides of a presentation as small thumbnails so that their order can be changed easily?

The correct answer is D, F5. Pressing F5 anywhere in a presentation closes the editing window and runs the slide show from slide one, whichever slide you were working on. To begin instead from the slide on the screen, the key is Shift + F5, and the pair F5 and Shift + F5 should always be learnt together.

Option A, Alt + F5, does not start an ordinary show from the beginning; in recent versions it opens Presenter View, where the speaker sees notes and a timer. Option B, Ctrl + P, is the print command in editing view, and inside a running show it turns the mouse pointer into a pen for writing on the slide, so it never starts the show. Option C, Alt + Tab, belongs to Windows rather than PowerPoint and merely switches between the open programs on the taskbar.

The correct answer is A, only (i) is false. Statement (i) is wrong because Ctrl + N opens a brand new, empty presentation; the key that inserts a new slide into the open presentation is Ctrl + M. Statement (ii) is true: PowerPoint 2016 can save or export a presentation as a PDF through Save As or Export, a facility Office has carried since the 2007 version.

Option B says only (ii) is false, which reverses the position of the two statements. Option C claims both are false, but the PDF facility plainly exists in PowerPoint 2016. Option D says neither is false, which would make Ctrl + N a slide-inserting key and is exactly the confusion the paper setter is testing. Remember the pair: Ctrl + N for a new file, Ctrl + M for one more slide.

The correct answer is C, .pptx. From PowerPoint 2007 onwards the default save format is the XML-based Open Office format, whose extension is .pptx, and PowerPoint 2016 follows it. Option A, .ppt, was the default of the older 97–2003 binary format and survives only for backward compatibility. Option B, .potx, is the extension of a design template, a file kept to start new presentations from rather than to hold one presentation. Option D, .ppsx, is a PowerPoint Show: the same content saved so that double-clicking it opens straight into the full-screen slide show instead of the editing window. A macro-enabled presentation, which appears as a distractor elsewhere, takes .pptm. Learn the four together, because papers mix them in a single question. In the hall, read the option list slowly: .pptx and .ppsx differ by a single letter, and that letter s stands for show.

The correct answer is A, Ctrl + M. It adds a fresh slide below the selected slide, using the layout of the current one. Option B, Ctrl + N, is the trap: it does not touch the open file at all but opens a new blank presentation in another window. Option C, Ctrl + D, duplicates whatever is selected, so with a slide selected in the thumbnail pane it makes a copy of that slide, complete with its text and pictures, rather than an empty new slide. Option D, Ctrl + K, inserts a hyperlink on the selected text or object, linking it to a web page, another slide or a file. The commonest examination error is choosing Ctrl + N here, so tie Ctrl + M to "one more slide".

The correct answer is B, Transitions. A transition is the visual effect between two slides — Fade, Push, Wipe, Split or Morph — and its gallery, duration, sound and advance timing all sit on the Transitions tab. Option C, Animations, is the near neighbour that papers use as a distractor: it applies effects to objects inside one slide, such as making a bullet fly in or a chart grow. Option A, Design, carries themes, variants, colours, fonts and the slide size, which change the look of slides but not the movement between them. Option D, Insert, is for adding content — tables, pictures, shapes, charts, headers, footers and slide numbers. Fix the rule in one line: between slides is a transition, within a slide is an animation. One more pointer worth carrying: the Transitions tab also holds the Apply To All button, which copies the chosen effect to every slide of the deck in one click.
