由于 vspace 和 hfill 导致的对齐问题

Question

面临对齐问题（3 和 4 未对齐），我怀疑这与 vspace 和 hfill 问题有关。请提供帮助。

\begin{enumerate}[\textbf{(\roman*)}]
\item Using a scale of 1 cm to 0.1 unit on each axis, plot $\lg y$ against $\lg x$ and draw a straight line graph. \hfill [3]
\item Use your graph to estimate the value of $k$ and of $n$. \hfill [4]
\vspace{\baselineskip}\newline\vspace{0.000001cm} \hfill [$k=84.2$, $n=1.35$]
\end{enumerate}

Answer 1

只需添加一个空行而不是应用\vspace即可解决问题：

代码：

\documentclass{article}

\begin{document}
\begin{enumerate}
\item Using a scale of 1 cm to 0.1 unit on each axis, plot $\lg y$ against $\lg x$ and draw a straight line graph. \hfill [3]
\item Use your graph to estimate the value of $k$ and of $n$. \hfill [4]

\hfill [$k=84.2$, $n=1.35$]
\end{enumerate}
\end{document}

Answer 2

\\这看起来像是一个（之后）实际上是合理的情况[4]：

\item Use your graph to estimate the value of $k$ and of $n$. \hfill [4]\\
\hfill [$k=84.2$, $n=1.35$]
