Arecent study compared property crime rates on various streets in a metropolitan city with the amount of traffic on them and their ease of access. although some believe that burglary is more common in low-traffic areas, the study showed that a house on a main road was more likely to be burglarized than one of comparable value on a less frequently traveled street requiring many turns to be reached. which of the following, if true, would best explain the results of the study ?
(a) burglars generally avoid residences with home security systems, which are more common in busy metropolitan areas.
(b) burglars in metropolitan areas who steal large, bulky items generally drive to the houses they intend to burglarize
(c) two weeks after a given burglar, the likelihood of another's accruing greatly increases for any house within a half-mile radius
(d) burglars spend most of their time performing routine, non criminal activities and will usually commit crimes on streets they frequently travel.
(e) burglars in urban environments often share information about which neighborhoods they are unlikely to be apprehended in .

Does this sound good? hey great britain, we need to talk. we’ve been through a lot these past couple of years and i don’t think that i would’ve made it this far without you but, i think it’s time that i tried to. don’t get me wrong, i think you’re a pretty great country! you’re smart, you’re funny, you're rich, and very dominant but, these past couple of years you’ve been a little too dominant. as each year goes by you become more and more self-absorbed. you’re only concerned about your own well-being. for example, when we get into arguments you always raise the taxes on paper and tea prices; it just isn’t fair. not only are you selfish but, you always want your buddies around. it’s not very fun cleaning up after you and your british soldiers (you guys never put the toilet seat down). they’re always popping up unexpected, and you always force me to let them stay for a couple of days. not to mention how irresponsible you are. i don’t like it when you force some of your responsibility on me. it’s not my fault that you got yourself into another war so, why should i have to pay for it? listen, in the beginning, what we had was good but, you and i aren’t so compatible anymore. i think it’s best if i took some time to be independent and think for myself for once. -yours truly, the states
