You have the following functions defined below (read them carefully!):

``````fun is-female(r): r["sex"] == "female"  end
fun kilograms(r): r["pounds"] / 2.2     end
fun is-heavy(r):  r["kilos"] > 25       end``````

The table `t` below represents four animals from the shelter:

name sex age fixed pounds

`"Toggle"`

`"female"`

`3`

`true`

`48`

`"Fritz"`

`"male"`

`4`

`true`

`92`

`"Nori"`

`"female"`

`6`

`true`

`35.3`

`"Maple"`

`"female"`

`3`

`true`

`51.6`

Match each Pyret expression (left) to the description of what it does (right). Note: one description might match multiple expressions!

 `` t.order-by("kilos", true)`` 1 A Produces a table containing Toggle, Nori and Maple, with an extra column showing their weight in kilograms ``````t.filter(is-female) .build-column("kilos", kilograms)`````` 2 B Produces a table containing Maple, Nori and Toggle (in that order) ``````t.build-column("kilos", kilograms) .filter(is-heavy)`````` 3 C Produces a table containing only Fritz. ``````t.filter(is-heavy) .build-column("kilos", kilograms)`````` 4 D Wonâ€™t run: will produce an error ``````t.build-column("kilos", kilograms) .filter(is-heavy) .order-by("sex", true)`````` 5 E Produces a table containing only Fritz, with two extra columns. ``````t.build-column("female", is-female) .build-column("kilos", kilograms) .filter(is-heavy)`````` 6 F Produces a table containing Maple and Fritz
