Police found that ninety percent of the burglaries and attempted burglaries over a five-year period in the city of Crowther occurred in houses that did not have burglar alarm systems. The police concluded that, in Crowther, the presence of a burglar alarm system is usually effective as a deterrent to burglary.
The conclusion reached by the police presupposes which of the following?
(A) The burglars entered houses only when they thought the 'occupants were away or asleep.
(B) The burglars entered houses that had burglar alarm systems only when they anticipated finding particularly valuable goods.
(C) When they entered a house that had no burglar alarm system, the burglars could take more time to search for valuables.
(D) Before they entered a house, the burglars could usually tell whether or not it had a burglar alarm system.
(E) The difference in the burglary rate between houses that had burglar alarm systems and those that did not have remained constant during the five-year period.
Kudos for the right answer and explanation

A is out of context, nothing can be said about the residents of the building
B is again out of context, nothing regarding the value of the stolen goods is mentioned
C is not right, taking more time is not the question asked, whether the burglary happened or not is the question.
D is right, the last line of the passage gives it away
E Out of context

The police concluded that, in Crowther, the presence of a burglar alarm system is usually effective as a deterrent to burglary.
this is an assumption question!
conclusion: the presence of a burglar alarm system is usually effective as a deterrent to burglary.
i.e just the presence of the alarm system discourages burglary
reasoning: 90% of the burglaries occurred in houses without alarm systems.
Underlying assumption: no other factors except for the absence of the alarm system encouraged the burglary to take place in those houses
answer choice analysis:
(A) The burglars entered houses only when they thought the 'occupants were away or asleep.
(180 option) this weakens the prompt as this option shows that the reason burglars attacked the houses was because the occupants were away or asleep and because of the absence of the alarm systems
(B) The burglars entered houses that had burglar alarm systems only when they anticipated finding particularly valuable goods.
this option doesn't prove as to why there are more burglaries in houses that have no alarm system vs houses that do
(C) When they entered a house that had no burglar alarm system, the burglars could take more time to search for valuables.
just because they get more time doesn't give a reason for a quick burglaries to happen at a house that contains the alarm system.
(D) Before they entered a house, the burglars could usually tell whether or not it had a burglar alarm system.
this is the correct answer!
(E) The difference in the burglary rate between houses that had burglar alarm systems and those that did not have remained constant during the five-year period.
This option is completely irrelevant as it doesn't provide any reasoning as to why burglaries were higher in houses that had no alarm system
