在任務環境中重置計數器

有人可以幫我重置下面程式碼中的計數器（？）嗎？答案部分應以 開頭#1。我確實需要

\RenewTasks[resume, style=custom,label-align=right]{tasks}(2)

在序言中。

謝謝。

\usepackage[a4paper, top=2cm, bottom=2cm]{geometry}
\usepackage{multicol, paralist, multirow, amsmath, amsthm, amssymb, amsfonts, ulem}

\DeclareInstance{tasks}{custom}{default}{

  label-format    =  \bfseries ,

  label-offset    = .3333em ,
  after-item-skip = 5pt
}
\RenewTasks[resume, style=custom,label-align=right]{tasks}(2)

This is a long word problem, more than one line. I can't seem to use rlap for this. I have to use another begin{tasks} section here. 
\end{tasks}

In Exercises 8-13, solve the polynomial equations. 
\begin{tasks}(2)
\task
$x(x+12) = 0$
\task
$(2x+1)(2x-1) = 0$

\task
$3x(x^2-7)$
\task
$5x^4(x^2+3)$
\task
$2x(2x^2+5x-1)$

$x=0, \, x = -12$
\task
$x = - \, \dfrac 12, \, x = \, \dfrac 12$

答案1

兩件事情：

要容納長項目，您不需要啟動新環境。只需使用\task*

\task*
This is a long word problem, more than one line. I can't seem to use rlap for this. I have to use another begin{tasks} section here.

[resume=false]其次，當您輸入答案時，您可以在本地傳遞該選項

Answers:
\begin{tasks}[resume=false](2)

在此輸入影像描述

順便說一句，您可以標記問題並使用，而不是硬編碼問題範圍\ref

作為替代方案，您可以定義這些：

\NewTasks[resume, style=custom,label-align=right]{questions}(2)
\NewTasks[style=custom,label-align=right]{answers}

並像這樣使用它們

\begin{questions}(3)
\task
$3x^3 - 21x$
\end{questions}

\begin{answers}(2)
\task
$3x^3 - 21x$
\end{answers}

使程式碼更具可讀性。\task如果您願意，您也可以更改分隔符號。詳細資訊請參閱手冊。
