Injuries Recorded at Two Factories, 2024

Factory	Workers	Injuries recorded
Almazar plant	1,250	75
Sergeli plant	400	16

An inspector reviewing two factories was told by the management at Almazar that its plant had the better safety record of the two. The published figures do not support that description:

Which choice most effectively uses data from the table to complete the text?

Sergeli recorded 6 injuries per 100 workers, while Almazar recorded 4. Almazar employs more than three times as many workers as Sergeli does. Almazar recorded 6 injuries per 100 workers, while Sergeli recorded 4. Almazar recorded 75 injuries against Sergeli's 16, more than four times as many.

Weeds Recorded per Square Metre After Two Growing Seasons

Plot	Before treatment	After two seasons
Cover crop sown	42	11
Mulch applied	39	18
Left bare (control)	44	40

A research farm compared two ways of suppressing weeds without herbicide, alongside a plot left untreated. The farm reported that sowing a cover crop had been the more effective of the two treatments tested, and the counts support this:

Which choice most effectively uses data from the table to complete the text?

the cover-crop plot recorded 11 weeds per square metre after two seasons, the lowest count in the table. the cover-crop plot fell by 31 weeds per square metre, against 21 on the mulched plot. the untreated plot fell by only 4 weeds per square metre over the same period. the mulched plot began with 39 weeds per square metre, fewer than either of the other two plots.

Fish Landed at a Port (tonnes)

Species	2015	2023
Herring	8,400	5,100
Mackerel	3,200	4,900
Cod	1,900	700

Total landings at the port fell between 2015 and 2023, and a local newspaper described the decline as affecting every part of the fleet. The port's own records show otherwise:

Which choice most effectively uses data from the table to complete the text?

herring landings fell from 8,400 tonnes to 5,100 tonnes over the period. mackerel landings rose from 3,200 tonnes to 4,900 tonnes over the same period. cod landings fell by 700 tonnes over the period. mackerel landings fell from 4,900 tonnes to 3,200 tonnes over the period.

Households Reporting a Vegetable Garden (percent of households surveyed)

District	2019	2024
Rural district A	71	66
Rural district B	68	64
Suburban district C	22	38

A survey of three districts found that the practice of growing vegetables at home is changing, though not in one direction. A researcher summarised the pattern by noting that the practice is spreading where it was rare and receding where it was common, since

Which choice most effectively uses data from the table to complete the text?

the suburban district rose from 22 to 38 percent while both rural districts fell by 4 or 5 points. the suburban district recorded 38 percent in 2024, still below either rural district. all three districts recorded a lower share in 2024 than in 2019. rural district A recorded the highest share of households with a garden in both years.

Average Wait for a Routine Appointment (days)

Clinic	Before online booking	After online booking
Clinic 1 (online booking added)	17	11
Clinic 2 (online booking added)	21	14
Clinic 3 (no change)	19	12

Two clinics in a district introduced online booking; a third kept its telephone system. The district's press release credited online booking with the shorter waits recorded afterwards. The figures give little support to that claim:

Which choice most effectively uses data from the table to complete the text?

the clinic that made no change cut its wait by 7 days, as much as either clinic that added online booking. Clinic 1 cut its average wait from 17 days to 11 days. all three clinics recorded a shorter wait after the change than before it. Clinic 2 recorded the longest wait of the three clinics before the change.

Solar Panels Installed and Electricity Generated, Two Provinces, 2024

Province	Panels installed (thousands)	Electricity generated (gigawatt-hours)
Province A	480	624
Province B	150	225

Two provinces published their solar figures for 2024. Province A announced that it was making better use of its installed panels than its neighbour. The published figures point the other way, since

Which choice most effectively uses data from the table to complete the text?

Province A generated 624 gigawatt-hours, nearly three times Province B's 225. Province B generated 1.5 gigawatt-hours per thousand panels against Province A's 1.3. Province A installed 480 thousand panels, more than three times as many as Province B. Province A generated 1.5 gigawatt-hours per thousand panels against Province B's 1.3.

Xatoni turi bo'yicha tahlil qiling

Xato turi	Nima qilish kerak
Xom sonni nisbat o'rniga oldim	60-dars. rate · share · better use · harder = bo'linma.
Jadvaldagi qiymatni o'zgarish deb oldim	61-dars. Jami ≠ o'sish. Ayirishni bajaring.
Yo'nalishni teskari o'qidim	61-dars. Ikki sonni solishtiring.
Nazorat ustunini e'tiborsiz qoldirdim	62-dars. O'zgarmagan ustun bekorga qo'yilmaydi.
O'zgarishdan oldin ham rost bo'lgan faktni tanladim	62-dars. «Bu avval ham shunday edimi?»
Bo'sh joydan oldingi bog'lovchini o'qimadim	63-dars. since · however · otherwise · bears this out.

💡 Maslahat: Bu mavzuda eng ko'p ball yeydigan bitta xato bor va u matematik emas: xom sonni nisbat o'rniga olish. Jadvalda «soni» va «umumiy soni» ustunlari birga tursa — SAT deyarli har doim bo'linmani so'rayapti.

Kalit so'zlar — Key vocabulary

Xulosa — Command of Evidence (Quantitative) mavzusi yakuni

Tartib: sarlavha → birlik → bog'lovchi → zid variantlar → da'voga tegishmi.
Son ≠ ulush. Bu mavzudagi eng qimmat xato.
Jadvaldagi qiymat o'zgarish emas — ayirishni bajaring.
O'zgarmagan ustun (nazorat) bo'lsa — javob uni ishlatadi.
«Bu o'zgarishdan oldin ham rost edimi?» — ha bo'lsa, dalil emas.
