How to display certain line of file only using head or tail in 1 command?

First month learning about the Linux terminal and it has been a challenge yet fun so far. We're learning by using a gameshell. I'm trying to display a certain line ( only allowed 1 command ) from a file only using the head or tail. I'm pretty about this answer:


Code:
head -23 history.txt | tail -1



However, it is not the good answer once I complete the gash check.

Any advice will help !

NAME
clasp - a conflict-driven nogood learning answer set solver SYNOPSIS
clasp [number][options] DESCRIPTION
This manual page documents briefly the clasp command. clasp is an answer set solver for (extended) normal logic programs. It combines the high-level modeling capacities of answer set program- ming (ASP) with state-of-the-art techniques from the area of Boolean constraint solving. The primary clasp algorithm relies on conflict- driven nogood learning, a technique that proved very successful for satisfiability checking (SAT). Unlike other learning ASP solvers, clasp does not rely on legacy software, such as a SAT solver or any other existing ASP solver. Rather, clasp has been genuinely developed for answer set solving based on conflict-driven nogood learning. clasp can be applied as an ASP solver (on LPARSE output format), as a SAT solver (on simplified DIMACS/CNF format), or as a PB solver (on OPB format). OPTIONS
These programs follow the usual GNU command line syntax, with long options starting with two dashes (`-'). A summary of options is included below. For a complete description, see <http://www.cs.uni-potsdam.de/clasp/>. -h, --help Show summary of options. -v, --version Show version of program. SEE ALSO
