Q230. Which key begins a PowerPoint slide show from its first slide?

[RRB JE CBT-2 (Civil), 22 April 2025, Shift 2]

1. F5
2. Alt + Tab
3. Ctrl + P
4. Shift + F5

Answer: A. F5

Explanation: F5 starts a PowerPoint slide show at the beginning, regardless of the slide selected in editing view. Shift + F5 generally starts at the current slide. Alt + Tab switches applications and Ctrl + P opens printing commands in many programs.

Q229. In Excel, what does COUNT() count?

[SSC CGL Tier-II 2024 (held 20 January 2025)]

1. Number of files stored
2. Number of duplicate cells
3. Cells containing numeric values
4. Number of printed pages

Answer: C. Cells containing numeric values

Explanation: COUNT returns the quantity of numeric entries in the supplied arguments or ranges, and generally ignores blank or textual cells. COUNTA instead counts nonempty cells of several types. Spreadsheet functions return calculated values and do not physically change worksheet data.

Q228. When a new row is inserted into an Excel worksheet, what happens to existing rows below the insertion point?

[SSC CGL Tier-II 2024 (held 20 January 2025)]

1. They are sent to the bottom
2. They shift right
3. They are overwritten
4. They shift downward

Answer: D. They shift downward

Explanation: Inserting an entire worksheet row creates space and moves existing rows from that position downward, preserving their contents. It does not overwrite the row’s original data. Formula references may adjust automatically when rows are inserted within referenced areas.

Q227. Which shortcut increases paragraph indentation in Microsoft Word 2010?

[SSC CGL Tier-II 2024 (held 20 January 2025)]

1. Ctrl + M
2. Ctrl + K
3. Ctrl + D
4. Ctrl + U

Answer: A. Ctrl + M

Explanation: Ctrl + M increases the left paragraph indent in Word. Ctrl + K inserts a hyperlink, Ctrl + D opens font-related controls in many Word versions, and Ctrl + U toggles underlining. Paragraph indentation controls spacing relative to the margin.

Q226. Which Word control sets text alignment to left, centred, right or justified?

[SSC CGL Tier-II 2024 (held 20 January 2025)]

1. Paragraph Alignment
2. Font Style
3. Line Spacing
4. Text Direction

Answer: A. Paragraph Alignment

Explanation: Paragraph alignment governs the horizontal position and distribution of text within a paragraph. Left, centre, right and justified alignment are distinct layout choices. Font style controls character appearance, while line spacing changes the vertical distance between baselines.

Q225. Which sequence starts a blank PowerPoint presentation through the application menu?

[SSC CGL Tier-II 2024 (held 20 January 2025)]

1. New, Blank Presentation, File
2. File, New, Blank Presentation
3. Blank Presentation, New, File
4. File, Blank Presentation, New

Answer: B. File, New, Blank Presentation

Explanation: From the File menu, choose New and then Blank Presentation to begin an empty presentation. Users can alternatively choose a design template at creation time. Starting with a blank presentation leaves the designer to select layouts and visual styles.

Q224. How do you leave PowerPoint slide-show view and return to editing?

[SSC CGL Tier-II 2024 (held 20 January 2025)]

1. Ctrl + S
2. Spacebar
3. Alt + Tab
4. Esc

Answer: D. Esc

Explanation: The Escape key closes the active slide-show presentation view and returns to the editor. Spacebar normally advances animations or slides, while Ctrl + S saves the presentation. Alt + Tab switches between windows rather than directly ending the slide show.

Q223. Which purpose most closely matches the role of ROM in a computer?

[SSC CGL Tier-II 2024 cycle (held 20 January 2025)]

1. Storing startup firmware
2. Saving all personal documents
3. Providing volatile working space
4. Replacing processor registers

Answer: A. Storing startup firmware

Explanation: Read-only memory, broadly including nonvolatile firmware storage, holds instructions that survive a power loss, such as boot firmware. RAM provides temporary working space. User documents are ordinarily stored on separate drives, not in the system’s boot firmware.

Q222. Consider these statements: 1. The CPU is commonly called the computer’s brain. 2. Its three main units are CU, ALU and cache memory. Which statement is correct?

[SSC CGL Tier-II 2024 cycle (held 20 January 2025)]

1. Both 1 and 2
2. Only 1
3. Only 2
4. Neither

Answer: B. Only 1

Explanation: Calling the CPU the brain of a computer is conventional because it controls and processes instructions. The claim that its three main functional units necessarily comprise a control unit, arithmetic logic unit and cache memory is not the standard elementary classification.

Q221. In a multipart MIME email, what does the Content-Type boundary mark?

[SSC CGL Tier-II 2024 cycle, held 20 January 2025]

1. Message’s total length
2. The limits between message parts
3. Sender’s authentication method
4. Maximum attachment size

Answer: B. The limits between message parts

Explanation: MIME multipart messages use a boundary delimiter to separate their individual parts, such as plain text and attachments. The boundary string does not specify maximum size or establish the sender’s identity.
