Hello
I need an expert's opinion on this. Is it because in the testimony, the person is not sure McGregor was scheduled to work on that day (he would very likely have been scheduled that day) makes the option "McGregor was scheduled to work at the building on the morning of Tuesday, July 6." wrong?
And is it because the person could reach to the conclusion that it was McGregor just by noticing his cap and his height, makes the 4th option correct?

­Yes, you are correct. We are looking at word 'implies', so the information in the para should imply that the witness assumes it to be true.

"McGregor was scheduled to work at the building on the morning of Tuesday, July 6": As correctly pointed out by you, the witness is not 100% sure on whether McGregor was scheduled to work that day. He just connects his impression of what he saw in the morning to a likelihood of McGregor being on work that day.

Now, in the sentence, "I knew it was McGregor by the man’s height and his long, slightly awkward steps,", he is 100% sure that it is McGregor. ...Correct for assumes to be true.

Of course, the wearing of hat plays a role in his testimony, and the hat being base ball cap has no role as McGregor was known to wear different types of caps. He may or may not have worn the base ball cap earlier. This negates the option that talks of hat 

For sure, assumes to be false is an easy one, as teh first option directly contradicts the statement made by witness.

Assume to be true:
locate the sentence that "I knew it was McGregor by the man’s height and his long, slightly awkward steps, and from the fact that he was wearing a hat", the witness assumes that he can distinguish McGregor from the other groundskeepers by his height, way of walking, and tendency to wear hats.

Assume to be false:
located the sentence that 'On Tuesdays there are always several groundskeepers scheduled to work on the grounds, and he would very likely have been scheduled that day.', it assumes that he was not alone / the only groundskeeper.

KarishmaB is option C wrong because it says "McGregor was scheduled to work at the building on the morning of Tuesday, July 6." and the testimony says that it is very likely that he was scheduled? Is the difference between 'very likely' and 'was scheduled' making this option wrong as the answer choice for 'Assumes to be true'??

­Assumes to be true: McGregor's height, way of walking, and tendency to wear hats distinguish him from the other groundskeepers.

The witness identified McGregor based on these specific characteristics, implying they believe these features set him apart from other groundskeepers.


Assumes to be false:  McGregor was the only groundskeeper scheduled to work at the building on Tuesday, July 6.

The witness states "On Tuesdays there are always several groundskeepers scheduled," implying they don't believe McGregor was the only one working. They only say McGregor "very likely" would have been scheduled, not definitively.­

Witness says, "I saw a man...", Can't we conclude that the witness assumnes the man was alone by purview of the fact that it said, 'a man'?

Just because the witness says "a man", it does not mean they assume:
  • The man exited alone, or
  • No one else was nearby or exiting before/after him.
The phrase "a man" simply describes who the witness saw, not the full context.

In fact, it's something they likely assume to be false or irrelevant; because their identification depends only on recognizable traits, not exclusivity of presence.

Understanding the Testimony
  • Witness says they saw a man exit at ~8:00am July 6.
  • They identified him as McGregor because of:
    • his height
    • awkward way of walking
    • wearing a hat (often a baseball cap)
  • Tuesdays → always several groundskeepers scheduled → likely McGregor was scheduled.
So the witness assumes certain things are true and also rules out other possibilities to conclude it was McGregor they saw.

Evaluate Each Statement
Let’s check each option in the table:
StatementTRUE or FALSE?Why
McGregor was the only groundskeeper scheduled to work at the building on Tuesday, July 6.FALSEWitness never says McGregor was the only one. In fact, they mention “several groundskeepers.” If McGregor were the only one, it would be easier to ID him. The witness implicitly assumes this is false.
McGregor exited the rear of the building in question alone at 8:00 on the morning of Tuesday, July 6.FALSEWitness didn’t say McGregor was alone. Not necessary for the identification. Doesn’t match an assumption explicitly.
McGregor was scheduled to work at the building on the morning of Tuesday, July 6.TRUEWitness says he’d “very likely have been scheduled.” Identification hinges partly on assuming McGregor was supposed to be there.
McGregor’s height, way of walking, and tendency to wear hats distinguish him from the other groundskeepers.TRUEAbsolutely crucial. Witness uses these physical traits to conclude it was McGregor. Must assume they’re distinctive.
McGregor often wore a baseball cap prior to the morning of Tuesday, July 6.TRUEAlso assumed true because witness says McGregor “always seemed to be wearing some kind of hat.” Helps ID him.

We need to pick one “Assumes to be true” and one “Assumes to be false.” The best are:
Assumes to be true:
McGregor’s height, way of walking, and tendency to wear hats distinguish him from the other groundskeepers.
Because otherwise, the witness couldn’t reliably conclude it was McGregor.
Assumes to be false:
McGregor was the only groundskeeper scheduled to work at the building on Tuesday, July 6.
Because the testimony says there are always several groundskeepers scheduled. The witness assumes McGregor wasn’t the only one, so identification is based on appearance, not exclusivity.

No that is in-correct. See - the person is mentioning 1 man with the peculiar way of walking.

How is A an assumption, isnt it already stated in the Q stem that : Several people work on Tuesdays, so Mr. Gregor cant work alone on Tuesdays, and an assumption should be unstated. Could you please clarify? KarishmaB MartyMurray

Good point.

(A) isn't exactly an assumption. It's more something that can be inferred to be false.

At the same time, since (A) is the only choice that clearly conflicts with the testimony, we can safely choose it for Assumes to be false.
