在任务环境中重置计数器

有人能帮我重置下面代码中的计数器吗？答案部分应该以 开头#1。我确实需要

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

在序言中。

谢谢。

\documentclass{book}
\usepackage[a4paper, top=2cm, bottom=2cm]{geometry}
\usepackage{multicol, paralist, multirow, amsmath, amsthm, amssymb, amsfonts, ulem}
\usepackage{tasks}[2014/07/20]

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

\begin{document}

In Exercises 1-8, factor the common factor in the polynomials. 
\begin{tasks}(3)
\task
$3x^3 - 21x$
\task
$5x^6 + 15x^4$
\task
$4x^3 + 10x^2 - 2x$

\begin{tasks}(1)
\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. 
\end{tasks}

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

Answers:
\begin{tasks}(2)
\task
$3x(x^2-7)$
\task
$5x^4(x^2+3)$
\task
$2x(2x^2+5x-1)$

\task
answer to the word problem
\task
$x=0, \, x = -12$
\task
$x = - \, \dfrac 12, \, x = \, \dfrac 12$
\end{tasks}

\end{document}

输出

答案1

两件事情：

为了容纳一个长项目，你不需要开始一个新的环境。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，您可以在输入答案时在本地传递选项

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

在此处输入图片描述

另外，你可以标记问题并使用，而不是对问题范围进行硬编码\ref

另外，您可以定义这些：

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

并像使用它们一样

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

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

这样代码就更易读了。\task如果愿意，您也可以更改分隔符。有关详细信息，请参阅手册。
