< !DOCTYPE html >
< html >
< body >
< h1 > The Fitness World Around Us - Spring Conference < /h1 >
< form action= " process.php " method= " post " >
< legend > Conference Registration Form < /legend >
< p > < label for= " name " > Name: < /label >
< input type= " text " id= " name " size= " 30 " maxlength= " 30 " value= " " / > < /p >
< input id= " food " placeholder= " Cuisine " list= " food-choice " size= " 40 " / > < br >
< datalist id= " food-choice " >
< option value= " Vegetarian " > Vegetarian < /option >
< option value= " Traditional " > Traditional < /option >
< option value= " Surprise Me " selected > Surprise Me < /option >
< /datalist >
< input type= " submit " >
< /form >
< /body >
< /html >
The correct solution must satisfy all three stated form requirements. The title " Conference Registration Form
" is supplied by the < legend > element in the first valid code segment. That same segment also includes the required attendee name field by using a < label > associated with an < input type= " text " > . The for= " name
" and id= " name " relationship makes the label programmatically connected to the input, which is the correct HTML form-accessibility pattern. For the food options, the correct choice is the segment that uses an < input
> element with a list attribute connected to a < datalist > element. This is required because the attendee must be able to select an option by using the mouse or type a value manually. A < select > element provides a fixed dropdown list, and radio buttons provide fixed clickable choices, but neither is the best match for a type-ahead list requirement. The < datalist > element supplies predefined options such as Vegetarian, Traditional, and Surprise Me while still allowing keyboard entry through the associated input field.

Correct Answer:

Explanation:
First blank: type
Second blank: pattern
Third blank: required
The first blank must be type because the question requires the input data type to be text, producing type= " text " . The second blank must be pattern because [0-9]{5} is a regular expression that permits exactly five numeric digits. The third blank must be required because the postal code field must be mandatory before the form can be submitted.

Correct Answer:

Explanation:
First drop-down: var xhr = new XMLHttpRequest();
Second drop-down: if(xhr.status===200){
Third drop-down: responseObject = JSON.parse(xhr.responseText);
The script must first create an XMLHttpRequest object, so the correct first selection is var xhr = new XMLHttpRequest();. This object performs the asynchronous request for menu.json. After the request finishes, the onload callback executes. The response should be processed only when the request succeeds, so the correct status check is if(xhr.status===200){; HTTP status 200 means the file was successfully retrieved.
Status codes 403, 404, and 500 represent forbidden access, missing resource, and server error conditions, so they are not appropriate for normal JSON processing. The JSON file is returned as plain text through xhr.
responseText, so it must be converted into a JavaScript object with JSON.parse(xhr.responseText). Once parsed, the code can access responseObject.menu[i].Entree, Price, and Description inside the loop and build the display output. responseXML is incorrect because the source file is JSON, not XML.

Correct Answer:

Explanation:
@media screen and (max-width: 480px) {
/* style rules go here */
}
The correct media query is @media screen and (max-width: 480px) {. The requirement says the style rule must apply to screen devices with a width of 480 pixels or less. In CSS media queries, screen identifies the media type, and (max-width: 480px) defines the upper viewport-width limit. This means the enclosed CSS rules apply when the viewport is 480 pixels wide or any smaller value, which is the standard mobile breakpoint behavior. @media screen and (width: 480px) is incorrect because it applies only when the viewport is exactly 480 pixels wide, not below it. @media screen display and (width: 480px) is invalid syntax because display is not used that way in a media query. @media screen-width: 480px is also invalid because it does not follow the required @media media-type and (feature: value) pattern.

Correct Answer:

Explanation:
First blank: < svg width= " 200 " height= " 200 " >
Second blank: < rect width= " 200 " height= " 200 "
Third blank: < circle cx= " 100 " cy= " 100 " r= " 50 "
Fourth blank: < /svg >
The correct solution uses SVG because SVG graphics are vector-based and can scale without pixel distortion when the page or viewport changes. A < canvas > element would require script-based drawing logic, which violates the requirement that JavaScript must not be required. An < img > or < picture > element can display an image, but those options do not define the rectangle and circle directly in markup. The outer container must therefore be < svg width= " 200 " height= " 200 " > . The blue square is created with < rect width= " 200 " height= " 200 " fill= " blue " / > , which produces a rectangle matching the required 200-by-200 dimensions.
The centered white circle must use SVG circle geometry: cx= " 100 " and cy= " 100 " place the center at the midpoint of the 200-by-200 square, and r= " 50 " creates the required 50-pixel radius. The final closing tag must be < /svg > .
