Question 1: No homework is enjoyable. Homework includes reading. Not fun is reading. The third statement is: if the first two claims are accurate.
- Uncertain
- True (Correct answer)
- False
Correct answer: True
This is a valid logical deduction. If 'No homework is enjoyable' means all homework falls into the category of 'not enjoyable,' and 'Homework includes reading' means reading is a type of homework, then it logically follows that reading must also be 'not fun' (not enjoyable). The conclusion is a direct consequence of the premises.
Question 2: The hiring procedure for the accounting department is now complete, and a training session is being planned. Recently hired staff members are all highly qualified. The trainees are all recently engaged workers. <br> What conclusion is logically drawn from the information presented above?
- All very well qualified employees are trainees
- Some of the trainees are not very well qualified
- All of the trainees are very well qualified (Correct answer)
- None of the trainees are very well qualified
Correct answer: All of the trainees are very well qualified
The premises state that 'Recently hired staff members are all highly qualified' and 'The trainees are all recently engaged workers' (meaning recently hired). Since all trainees fall into the category of 'recently hired workers,' and all 'recently hired workers' are 'highly qualified,' it logically follows that 'All of the trainees are very well qualified.' This is a direct application of the given information.
Question 3: Compared to black fish, silver fish can swim more quickly. Compared to black fish, the gold fish can swim more quickly. Compared to silver fish, the gold fish can swim more quickly. The third statement is: if the first two claims are accurate.
- Uncertain (Correct answer)
- True
- False
Correct answer: Uncertain
The first two statements establish that both silver fish and gold fish are faster than black fish. However, they provide no information to compare the speeds of silver fish and gold fish relative to each other. Gold fish could be faster, slower, or the same speed as silver fish, based solely on the given premises. Therefore, the third statement is uncertain.
Question 4: Fall is when deciduous trees lose their leaves. All year long, conifers maintain their foliage. Deciduous conifers are trees. The third statement is: if the first two claims are accurate.
- Uncertain
- True
- False (Correct answer)
Correct answer: False
The premises define deciduous trees as those that lose their leaves in fall and conifers as trees that maintain their foliage all year long. The term 'deciduous conifers' creates a contradiction based on these definitions, as it would imply a tree that both loses and keeps its leaves. Therefore, the statement 'Deciduous conifers are trees' is logically false given the provided definitions.
Question 5: All information is useful information. Some websites are of little use. Some websites lack informative content. The third statement is: if the first two claims are accurate.
- Uncertain
- True (Correct answer)
- False
Correct answer: True
If 'All information is useful information,' and 'Some websites are of little use,' then those 'little use' websites must contain something other than useful information, or lack useful information. Therefore, it logically follows that 'Some websites lack informative content' because if they contained useful information, they wouldn't be of little use. The conclusion is a direct consequence of the premises.
Question 6: Every rabbit has fur. Pet rabbits exist. Pets can have fur. The third statement is: if the first two claims are accurate.
- Uncertain
- True (Correct answer)
- False
Correct answer: True
The first premise states 'Every rabbit has fur,' and the second premise states 'Pet rabbits exist.' Since pet rabbits are a subset of all rabbits, and all rabbits possess fur, it logically follows that pet rabbits also have fur. Therefore, the conclusion 'Pets can have fur' is true, as pet rabbits are an example of pets that have fur.
Question 7: The following justification is insufficient: <br> <br> All emails sent by a company are secure, according to the statement. <br> <br> Therefore, every client request made by the company is secure.<br> <br> Which of the following sentences completes the previous argument and establishes the validity of the conclusion?
- All e-mails sent by an organization are client requests
- All client requests are sent by e-mail (Correct answer)
- Some client requests are not secure
- None of the above
Correct answer: All client requests are sent by e-mail
The argument states that 'All emails sent by a company are secure' and concludes that 'every client request made by the company is secure.' To make this conclusion logically valid, we need a premise that connects 'client requests' to 'emails sent by a company.' If 'All client requests are sent by e-mail,' then because all emails are secure, all client requests (being emails) must also be secure, thus completing the argument.
