Option A shows the correct basic syntax for jsp:useBean with the id and class attributes properly specified. Option B incorrectly uses 'property' instead of 'class' and has an equals sign typo. Option C incorrectly uses 'name' instead of 'id'. Option D incorrectly uses 'beanName' without the proper context and omits the required id attribute.

Both syntax examples (1 and 2) are valid. In option 1, setProperty is nested inside the useBean body. In option 2, setProperty appears after the useBean tag closes. Both approaches work correctly - the nested approach is more compact while the separate approach is more flexible. Therefore option C 'both' is correct.

The jsp:getProperty action requires exactly two attributes: 'name' (the bean identifier matching the useBean id) and 'property' (the specific property name to retrieve). Option D correctly identifies these two required attributes. Options A, B, and C list incorrect attribute combinations.

The jsp:include action uses the 'page' attribute (specifying the relative URL to include) and the optional 'flush' attribute (controls whether the buffer is flushed before inclusion). Option D correctly identifies these attributes. Options A and B list attributes used by other JSP actions (useBean), and option C incorrectly uses 'file' instead of 'page'.

The Macintosh introduced the mouse as a standard input device in 1984, revolutionizing personal computing interaction. While computers had screens and speakers before, and printers were common peripherals, the mouse was the groundbreaking innovation that made the Macintosh user-friendly and accessible to non-technical users.

The Mac Plus was the second major Macintosh model, released in 1986. It featured significant improvements over the original Macintosh including expandable memory up to 4MB and a built-in SCSI port. The Mac II was actually a later model (1987), and options like 'Mac 2.0' and 'Mac Ultra' were not actual model names in Apple's lineup.

Snow Leopard was the seventh major release of Mac OS X, version 10.6, released in 2009. Apple uses big cat names for their OS versions, and Snow Leopard followed Leopard (10.5). Options like 'Celtic Frost', 'Frost Giant', and 'Ice Titan' are not actual Mac OS X version names.

Google acquired Android, Inc. in August 2005 for approximately $50 million. This acquisition brought Andy Rubin and the Android team into Google, setting the stage for Android's development as a mobile operating system. The timing is crucial - it was well before the iPhone announcement in 2007, showing Google's early interest in mobile platforms.

Android co-founder Andy Rubin helped develop the T-Mobile Sidekick (also known as Danger Hiptop) before founding Android. The Sidekick was an innovative early smartphone with a focus on messaging and web access, which influenced Rubin's vision for Android. This is in contrast to BlackBerry, iPhone, or Palm Pilot, which were developed by different companies.

The HTC Dream, also known as the T-Mobile G1, was the first commercially available Android phone, released in October 2008. While the Motorola Droid, Samsung Galaxy line, and Google Nexus One came later, the HTC Dream holds the distinction of being Android's commercial debut. The phone featured a unique sliding keyboard design and ran Android 1.0.

At the time of this question's context, approximately 57% of applications in the Android Market were free. This high percentage of free apps was a distinguishing feature of Android compared to iOS App Store, reflecting Android's strategy of rapid app adoption through free applications supported by ads or in-app purchases.

Android-based devices ranked number one in units sold per month during this period, surpassing BlackBerry, iOS, and other mobile operating systems. This reflected Android's strategy of licensing to multiple manufacturers, leading to broad market penetration. The question's context appears to be from around 2010-2011 when Android overtook BlackBerry in market share.

Gingerbread (Android 2.3) was the code name for the Android version released in December 2010. Android versions are named alphabetically after sweet treats, and Gingerbread followed Froyo (Frozen Yogurt). The question mentions October 2010, but Gingerbread was actually released later that year - this reflects the announcement or expected release timing.

After Gingerbread (2.3), the next two Android versions were Honeycomb (3.0, released February 2011) and Ice Cream Sandwich (4.0, released October 2011). Honeycomb was tablet-focused, while Ice Cream Sandwich unified phone and tablet experiences. Options like 'Sugar Smacks', 'Honeypot', and 'Candy Cane' are not actual Android code names.

The BlackBerry 8900 was marketed as the BlackBerry Javelin in Asian markets. BlackBerry often used different code names for the same model in different regions - the 8900 series was part of the Curve line. Options like 'Leopard', 'Jaguar', and 'Pearl' don't match the Asian market name for this specific model, though Pearl was a different BlackBerry series.

The first wireless communication device was Alexander Graham Bell's photophone invented in 1880, which transmitted voice on a beam of light. While the first mobile cellular phone came much later (1973), the photophone represents the earliest wireless phone technology.

Research In Motion (RIM), the company behind BlackBerry devices, used Intel processors in their early smartphones. Intel was a major processor manufacturer that supplied chips for various mobile devices.

Research In Motion (RIM) was a Canadian telecommunications company founded by Mike Lazaridis and Douglas Fregin in 1984. RIM is best known for developing the BlackBerry smartphone.
