質問 # 21
A form has four buttons with a class of item. You need to apply an event listener to all buttons to invoke the moveElement function when a button is pressed. Your code must ensure bubble capture.
Complete the markup by selecting the correct option from each drop-down list.
Note: You will receive partial credit for each correct selection.
正解：
解説：
Explanation:
First drop-down: " click " ,
Second drop-down: moveElement,
Third drop-down: false,
The correct event listener syntax is addEventListener(type, listener, useCapture). The first argument must be " click " because the function must run when a button is pressed. The second argument must be moveElement, not moveElement(), because the event listener expects a function reference. Using parentheses would call the function immediately while the page is loading instead of waiting for the user to press a button. The third argument controls the event phase. false means the listener runs during the bubbling phase, which is the normal behavior for button click handling. true would register the listener for the capturing phase instead.
Since the code uses document.querySelectorAll( " .item " ), it selects all elements with the class item. The for loop then attaches the same click listener to each selected button individually. This ensures that all four buttons invoke moveElement when clicked.

You want to position a specific element so that it always directly follows the previous element, which is positioned by default, regardless of the viewport characteristics. Which positioning method should you use?
正解：D
解説：
The correct positioning method is static. In CSS, position: static is the default positioning behavior for elements. A statically positioned element remains in the normal document flow, meaning it is laid out according to the order of the markup and directly follows preceding elements unless another layout rule changes that flow. MDN defines static positioning as placing the element according to the normal flow of the document, with top, right, bottom, left, and z-index having no effect. This matches the requirement that the element always directly follows the previous default-positioned element and does not depend on viewport characteristics. absolute removes the element from normal flow and positions it relative to a containing block.
fixed also removes it from normal flow and positions it relative to the viewport. sticky starts in normal flow but changes behavior relative to a scrolling ancestor when a threshold is crossed.

質問 # 23
Which two statements correctly describe media queries? Choose 2.
正解：A、D
解説：
Media queries support responsive web design and allow different CSS rules to be applied at different screen sizes, device characteristics, or breakpoints. MDN describes media queries as a CSS mechanism for applying styles depending on media type and device or viewport characteristics, including width, height, resolution, and orientation. This is the foundation of responsive design because a page can adapt its layout for phones, tablets, laptops, and desktop displays without changing the HTML document. Breakpoints are the points where the design changes; MDN identifies them as the points where a media query is introduced to improve layout behavior across viewport sizes. Statement A is not generally correct because media queries are primarily a styling and layout mechanism, not a direct performance optimization. They can sometimes help avoid unsuitable layouts, but performance improvement is not their defining purpose. Statement D is incorrect because media queries are CSS rules; they do not execute or dynamically process JavaScript code. References

質問 # 24
You need to display the following user interface:
Motorcycle
Truck
Boat
Car
Bicycle
Complete the markup by selecting the correct option from each drop-down list.
正解：
解説：
Explanation:
First drop-down: datalist
Second drop-down: vehicles
Third drop-down: < /datalist >
The correct element is < datalist > because the interface requires a text input that provides selectable suggestions while still allowing the user to type. The < input > element uses list= " vehicles " , so it must be connected to a < datalist > element whose id is exactly vehicles. The id cannot be vehicle, because vehicle is already the input element's own identifier and does not match the value used by the list attribute. The < option
> elements inside the datalist define the suggested values: Motorcycle, Truck, Boat, Car, and Bicycle. ul, ol, and li are list-markup elements and do not create input suggestions. select would create a fixed dropdown list, but it would not match the editable input-with-suggestions behavior shown. The closing tag must match the opening datalist element, so the final selection is < /datalist > .
質問 # 25
The development team just released a new version of an app for your team to test. Which three tasks should you perform during testing? Choose 3.
正解：B、D、E
解説：
The correct testing tasks are to verify application functionality, find defects, and ensure the app meets design specifications. Testing occurs after development produces a build and before acceptance or deployment decisions are made. Its purpose is to compare the implemented application against expected behavior, requirements, and design specifications. Option A is correct because functional testing confirms that user workflows, controls, validation rules, scripts, and page interactions work as intended. Option C is correct because defect discovery is a core testing responsibility; testers identify failures, inconsistencies, regressions, and unexpected behavior so the development team can correct them. Option D is correct because the app must be evaluated against the documented design, including layout, navigation, responsiveness, accessibility expectations, and feature behavior. Asking customers to submit bugs or feature requests is a feedback or product-management activity, not the primary task of an internal test cycle immediately following a development release. Checking syntax errors is primarily handled during development, linting, editing, or build processing; a released test build should already parse and execute sufficiently for functional testing.
