Death in the car:A man was shot to death while in his car. There were no powder marks on his clothing, which indicated that the gunman was outside the car.

-
The maid and the cook are responsible.

Correct Answer
A. The man bought only a one-way ticket for his wife whereas he bought a two-way ticket for himself.Explanation
The travel agent was able to determine that it was a murder because the man bought a one-way ticket for his wife and a two-way ticket for himself. This suggests that the man intended to return from the trip alone, indicating premeditation and suspicion of foul play.Rate this question:

Take the cash and leave the wallet
-
Look around for the owner and return it
-
Keep the wallet without taking the cash
-
Leave the wallet where it is
Correct Answer
A. Look around for the owner and return itExplanation
The correct answer is "Look around for the owner and return it." When you find a wallet, the ethical choice is to return it to its rightful owner. Taking the money and leaving the wallet is theft, and keeping both would compound this action. Returning the wallet shows integrity and honesty. Additionally, the wallet could contain identification or credit cards, which would help the owner retrieve it. The best course of action is to act responsibly, ensuring that the wallet is returned or turned in to the proper authorities if the owner is not immediately identifiable.Rate this question:

Three spies: Three spies, suspected as double agents, speak as follows when questioned: Albert: “Bertie is a mole.” Bertie: “Cedric is a mole.” Cedric: “Bertie is lying.” Assuming that moles lie, other agents tell the truth, and there is just one mole among the three. Who is the mole?
-
Albert
-
Bertie
-
Cedric
-
No one
Correct Answer
A. AlbertExplanation
Let's analyze the statements:
Albert: "Bertie is a mole."
If Albert is telling the truth, then Bertie is a mole.
If Albert is lying, then Bertie is not a mole.
Bertie: "Cedric is a mole."
If Bertie is telling the truth, then Cedric is a mole.
If Bertie is lying, then Cedric is not a mole.
Cedric: "Bertie is lying."
If Cedric is telling the truth, then Bertie is lying (not a mole).
If Cedric is lying, then Bertie is telling the truth (a mole).
Now, let's consider the possibilities:
If Bertie is the mole, then both Albert and Cedric are telling the truth. However, this contradicts the assumption that there is just one mole.
If Albert is the mole, then Cedric is telling the truth. This aligns with the assumption of only one mole.
If Cedric is the mole, then Albert is lying (as the mole should). This also aligns with the assumption of only one mole.
Therefore, the conclusion is that Albert is the mole according to the consistent scenario where only one spy is a mole, and the statements align with the roles of truth-tellers and liars.Rate this question:

A friend claims they missed your call but their phone's battery was dead. What could this suggest?
-
They didn’t want to answer your call.
-
Their phone genuinely ran out of battery.
-
The phone malfunctioned.
-
The call was never made.
Correct Answer
A. They didn’t want to answer your call.Explanation
The correct answer is "They didn’t want to answer your call." When a person says their phone’s battery died but you notice they didn’t pick up a call, it likely means they were avoiding answering it. This excuse is commonly used to avoid uncomfortable or unwanted conversations. It implies that the person may have been deliberately ignoring your call for reasons other than the phone’s battery status. Such behavior suggests a lack of interest in communication, and the real reason for avoiding the call could be personal or related to the conversation topic.Rate this question:

A person walks into a room and immediately goes to the fridge to grab a drink. They’ve never been to your house before. What can you infer?
-
They’ve been in your house before and feel comfortable.
-
They were thirsty and just happened to go for a drink.
-
They are exploring and want to look for food.
-
They might be looking for something specific.
Correct Answer
A. They’ve been in your house before and feel comfortable.Explanation
The correct answer is "They’ve been in your house before and feel comfortable." The immediate action of opening the fridge in a new house suggests a familiarity with the space. If a person instinctively goes for a drink without hesitation or asking, it implies they are comfortable in the environment, possibly because they have visited before. Such behavior demonstrates that the person is accustomed to the house’s layout and knows where the fridge is located. The actions reveal an assumption of comfort, suggesting prior visits, and a sense of belonging in your home.Rate this question:

Famous chemist murdered: A very famous chemist was found murdered in his kitchen today. The police have narrowed it down to six suspects. They know it was a two-man job. Their names: Felice, Maxwell, Archibald, Nicolas, Jordan, and Xavier. A note was also found with the body: ’26-3-58/28-27-57-16′. Who are the killers?
-
Maxwell and Nicolas
-
Felice and Nicolas
-
Jordan and Felice
-
Archibald and Maxwell
Correct Answer
A. Felice and NicolasExplanation
The note left behind is a clue that can be deciphered using the periodic table of elements. The numbers correspond to the atomic numbers of elements on the periodic table.
The sequence ‘26-3-58/28-27-57-16’ translates to:
26-3-58 as Iron-Lithium-Cerium (Fe-Li-Ce)
28-27-57-16 as Nickel-Cobalt-Lanthanum-Sulfur (Ni-Co-La-S)
So, the killers are Felice and Nicolas. The first part of the note spells out Felice’s name using the symbols of the elements, and the second part spells out Nicolas’s name in the same way.Rate this question:

A valuable artifact has been stolen from a museum. The security footage shows three suspects near the scene of the crime. Detective Smith carefully analyzes the footage and notices a unique tattoo on one suspect's wrist, matching the description given by a witness. Another suspect has a history of art theft but claims to have an alibi. The third suspect, a museum employee, was off-duty during the incident. Who should Detective Smith focus the investigation on, based on the available information?
-
The suspect with the unique tattoo.
-
The suspect with a history of art theft but an alibi.
-
The museum employee who was off-duty.
-
Continue investigating all suspects without focusing on one.
Correct Answer
A. The suspect with the unique tattoo.Explanation
Based on the available information, Detective Smith should focus the investigation on the suspect with the unique tattoo. The tattoo matches the witness description, making this suspect a primary person of interest. While the suspect with a history of art theft is suspicious, having an alibi raises doubt. The museum employee, being off-duty, is less likely to be involved. Focusing on the suspect with the unique tattoo allows the detective to narrow down the investigation and gather more specific evidence related to this individual's potential involvement in the theft.Rate this question:

You see a person repeatedly checking their watch while talking to someone. What might this suggest?
-
They are bored and waiting to leave.
-
They are anxious about being late for something.
-
They have a habit of checking their time frequently.
-
They are interested in the conversation but distracted.
Correct Answer
A. They are anxious about being late for something.Explanation
When someone repeatedly checks their watch during a conversation, it often suggests they are worried about the time—possibly anxious about being late for another commitment. While it could also hint at boredom or distraction, the most direct and commonly interpreted reason is concern about timing. This nonverbal cue typically signals that their attention is divided due to time pressure rather than deep engagement in the current interaction.Rate this question:

A man is found murdered on a Sunday. The police question the wife, the chef, the gardener, and the maid. Each gives the following alibi: Wife: "I was sleeping." Chef: "I was cooking breakfast." Gardener: "I was planting flowers." Maid: "I was getting the mail." Who is the killer?
-
The Wife
-
The Chef
-
The Gardener
-
The Maid
Correct Answer
A. The MaidExplanation
The Maid because her alibi doesn’t make sense. She claimed she was "getting the mail" when the murder occurred on a Sunday—a day when mail is not delivered in most countries, including the United States. This inconsistency makes her statement suspicious and points to her being the likely culprit. In detective reasoning, false or impossible alibis often reveal the truth. The others gave plausible explanations, but the maid’s stands out as clearly flawed.Rate this question:

Sherlock Holmes and the Crimson Brothers: One snowy night, Sherlock Holmes was in his house, sitting by a fire. All of a sudden a snowball came crashing through his window, breaking it. Holmes got up and looked out the window just in time to see three neighborhood kids who were brothers running around a corner. Their names were John Crimson, Mark Crimson, and Paul Crimson. The next day Holmes got a note on his door that read "? Crimson. He broke your window." Which of the three Crimson brothers should Sherlock Holmes question about the incident?
-
He should question John Crimson
-
He should question Paul Crimson
-
He should question Mark Crimson.
-
He should question all three brothers.
Correct Answer
A. He should question Mark Crimson.Explanation
The note left on Sherlock Holmes's door is a clue. The question mark has 3 points, and the name "Mark" has 3 letters. This suggests that Mark Crimson is the one who broke the window and that the note was written by one of his brothers.Rate this question:

Anonymous call: Acting on an anonymous phone call, the police raid a house to arrest a suspected murderer. They don't know what he looks like, but they know his name is John and that he is inside the house. The police bust in on a carpenter, a lorry driver, a mechanic, and a fireman playing cards. Without hesitation or communication of any kind, they immediately arrest the fireman. How do they know they've got their man?
-
The fireman's name is John.
-
The carpenter stole the money.
-
The mechanic did it.
-
The lorry driver did it.
Correct Answer
A. The fireman's name is John.Explanation
The police know they've got their man because the fireman's name is John. The anonymous call informed them that the suspect's name was John, and upon entering the house, they found four individuals playing cards. Without any hesitation or communication, the police arrest the fireman, indicating that they identified him as the suspect based on his name. The other options, such as the carpenter stealing money, the mechanic being responsible, or the lorry driver being the culprit, are not supported by the information provided in the question. The question only states that the police were looking for a suspected murderer named John, and they arrested the fireman named John, suggesting that the fireman was indeed the suspect they were looking for.Rate this question:
