問題９下の文章は雑誌のコラムです。テレビや雑誌では、よく「血液型性格判断」が取り上げられます。これは、血液型によって性格が決まっている、言い換えれば、血液型がわかれば大体の性格もわかるという50 です。その血液型性格判断によると、人の性格は、A 型、B 型、O 型、AB 型の血液型ごとに決まっているのだそうです。しかし、この世界には何十億人もの人が51－a、人の性格をたった4 種類に分類することが51－b。血液型は親から子への遺伝によって、4 種類のうち、どの型になるかが決まります。つまり、52－aは生まれてから死ねまで、変わることはほぼありません。一方、52－b はどうでしょうか。52－c に関して言えば、子どものときは我慢が苦手だった子が、成長とともに我慢できるようになるといったことも少なくないでしょう。また、ある調査によると、自分の血液型がどんな性格かということを聞いて、知らないうちに自分の性格がその性格に近づいてしまっているということもあるそうです。「私はA 型だから、こういう性格なんだ」という思い込みで、性格が作られている可能性も否定できないというのです。53、性格と血液型に関係はあると言えるかもしれませんが、それは血液型で性格が決まるということではありません。こう考えると、やはり、血液型によって性格がたった4 種類に分けられるとは54。

Crash-Prone The Solution Could Be Windows XP;
But does It Make Sense to Upgrade Your Operating System

You can hardly turn on the television or click on a Web page without seeing a colorful ad for Microsoft’s new Windows XP operating system, which launched on Oct. 25.
So, now that the long-awaited XP is here, what are you going to do about it Should you upgrade, and if you do, how hard is it and what are the potential drawbacks The decision is pretty easy if you really need a whole new Windows PC. They all come with XP preloaded, and in my tests of a few such models, they seemed to work well. I’m writing this on my own new personal computer, a Dell that came preloaded with Windows XP, and it worked great right out of the box.
The only downside is that if you’re keeping older printers, scanners and other peripherals, you may have to download new "drivers" — the small programs that allow a PC and a peripheral to interact. XP contains many of the drivers for recent-model printers and the like, sparing you from even digging out the disks that came with them. But if you have older equipment, you may have to download new drivers, because the original software that came with the hardware might not work with Windows XP.
It’s harder to decide what to do about XP if you have a PC that doesn’t need replacing. If you’re happy with the way things are working, don’t upgrade. It’s never a trivial thing to change operating systems, and you shouldn’t do it without a reason.
However, there are two big limitations in prior versions of Windows that XP does fix, and that might make an upgrade worthwhile. These are stability — that is, the ability not to crash, or at least to do so rarely — and compatibility. Windows 98 and Windows ME, the previous consumer versions, had wide compatibility with consumer software and peripherals, but lousy stability. Windows 2000, the prior business version, had great stability, but limited compatibility with consumer software and add-on hardware.
Windows XP is designed to combine the stability of Windows 2000 (with which it shares underlying code) with the compatibility of Windows 98 and Windows ME, and in my experience, it does a good job at that. So if you need more reliability or compatibility than your current version of Windows supplies, an upgrade may be in order.
But there’s a catch. Microsoft says that an XP upgrade will really be sensible only if your PC is two years old or less — built after 1999. And you need at least a 300MHz processor and 128 megabytes of memory, though I recommend at least 192MB, and 256MB is even better. Also, you’ll need a roomy hard disk — Windows XP alone will suck up 1.5 gigabytes.
So there are only a limited number of PCs for which upgrading makes sense, and you may have to invest in beefing yours up first.
Not only that, but you must have Windows 98, Windows ME or Windows 2000 on your current system to upgrade. If you have Windows 95 and somehow still have a new enough machine to qualify, you have to buy a very expensive, "full" version of Windows XP, basically wipe out your whole hard disk and start from scratch with XP, losing all your installed programs and settings.
If you’re good to go, you next have to decide which upgrade version of XP is right for you — the $99 Home Edition or the $199 Professional. The differences between them are surprisingly small, and 95 percent of home and small-business users will be fine with the home version. Buy the pro version only if you are running more than a modest network or need special security features.
Note that if you have Windows 2000, or NT 4.0, you can upgrade only to Windows XP Professional, not the Home Edition. If you have Windows 98 or ME, you can choose either flavor of XP.
In my tests, which included five PCs running all the main older versions; the Windows XP upgrades, both home and pro, went very smoothly.
The process took about an hour in each case, and the installation software was friendly and clear in its instructions and progress reports.

Windows XP Home Edition is appropriate for ______.
A. all the main older versions of Windows
B. Windows 98 or ME
C. Windows 2000
D. NT4.0
