Please complete these two exercises:

Exercise $1$:

a$)$ In Example $7\mathrm{.}9,$ how many data records result from the inner join of four tables in Example $7\mathrm{.}9?$

$1)5$ data records with PR$1,$ PR$2,$ PR$3,$ PR$4,$ PR$5.$

$2)6$ data records with PR$1,$ PR$2,$ PR$3,$ PR$4,$ PR$5,$ PR$6.$

$3)4$ data records with PR$1,$ PR$2,$ PR$3,$ PR$4.$

b$)$ In Example $7\mathrm{.}9,$ how many data records result from after selecting data records with Disease$1$ from the result of the inner join?

$1)4$ data records with PR$1,$ PR$2,$ PR$3,$ PR$4.$

$2)5$ data records with PR$1,$ PR$2,$ PR$3,$ PR$4,$ PR$5.$

$3)6$ data records with PR$1,$ PR$2,$ PR$3,$ PR$4,$ PR$5,$ PR$6.$

c$)$ In Example $7\mathrm{.}9,$ how many groups of data records after GroupBy MedicineName is applied?$$

$1)3$ groups with M$1,$ M$2,$ and M$3.$

$2)2$ groups with M$1$ and M$3.$

$($Example $7\mathrm{.}9$ are the first two pictures$)$

Exercise $2$: In Example $7\mathrm{.}12,$ write an expression for the Field row and an expression for the Criteria row to select data records with the value of DateOfVisit in the current month.

$1)$ Field Row: Month$($DateOfVisit$)|$ Criteria Row: Month$($Date$())$

$2)$ Field Row: Month$($Date$())|$ Criteria Row: Month$($DateOfVisit$)$
